Hardware Implementation of the Optimal Ldpc Decoder 000_14.pdf

Low Density Parity Check (LDPC) codes become more useful in modern infocommunication systems because of their error-correcting capability. At the present time, LDPC codes have reached Shannon’s limit. Moreover, the application of such codes unlike the turbo codes don’t have any license limitations. These factors have become the cause of growing interest to LDPC codes. Despite an easy way of the codec implementation, soft decoding of LDPC codes is a complex computational process. This article deals in more detail with the main problems concerning the hardware implementation of LDPC decoder and the ways of their solving. It also demonstrates the simulation results of different ways to decoder implementation and the comparison of these ways. Furthermore, the article presents the method of LDPC codes list decoding that reduces materially computational load on decoder and speeds up its work operation. The use of various procedures and mechanisms described in the article will help to generate the optimal LDPC code decoder designed for a certain task.

Estimation of Optimal Multiservice Telecommunications Network Router Buffer Size 000_5.pdf

The article deals with different approaches to the estimation of optimal multiservice network router buffer size. It has been found that in plenty of existing approaches the most rational one should take into account the real traffic spectrum jointly with the facilities providing quality of service when optimal buffer size estimating. The qualitative traffic control can be realized only under conditions of prioritizing multimedia data flows in a format of fast and slow buffers. In addition, to provide the guaranteed quality of service during short-period traffic pulsations it is necessary to calculate the router buffer size taking into account packet loss prevention. The achieved conclusions can be used for the development of multipurpose integrated information management systems.

Straightaway Explicit Fir Programming Algorithm for Filtering, Smoothing, and Prediction 000_9.pdf

In this paper, we develop a straightaway explicit finite impulse response (FIR) programming algorithm for the filtering, smoothing, and prediction of signals containing a nonrandom component or their derivatives as an admissible alternative to previously known methods. The distinctive property of the algorithm is that it determines the FIR directly via the Chebyshev polynomials arising in the finite sample based quadratic approximation numerical analysis thus alleviating the problem of normal equations solution in the ordinary least squares (OLS) method. Using the Chebyshev polynomials gave an option of obtaining the following: short and explicit calculation formulae for FIR, i. e. for the conversion device weighting coefficients, including a possibility of estimating the signal derivatives; short formulae for filter-predictor smoothing factors; necessary memory size design procedure for filter-predictors of arbitrary astaticism order. Results obtained are useful for practical calculations when making a selection of filtering or prediction formula, i.e. while programming a FIR conversion device, and they can find practical use in adaptive devices.

Unification of Redundant Code Decoding Algorithms in Integrated Information-management Systems 39_2.pdf

The increasing requirements for control of integrated information-management system elements are caused by the need of application of communication protocols that are heterogeneous in terms of organization and control cycle duration. Thereupon, it is reasonable to use a set of error-controlled codes differing in redundancy, and processed on a common hardware platform, in similar systems to prevent errors in real-time information. To implement this concept it is expedient to use short block codes. They are applicable in the process of small data transmitting and they can be easily transformed to protect a large bulk of data using the cascaded coding technology or on the basis of product codes in 3D or in higher dimensions. The code sequences shortening at specified requirements in terms of data adequacy leads to a need of the flexible synthesis of information on signals received from a continuous communications channel and of soft iterative algorithms of the selected redundant codes processing. Polar code constructions meet this requirement. The paper offers to use the proper code combinations space clustering in order to reduce the polar code combinations processing time interval. The text gives valuable information on a clustering mechanism and cluster number security variants when transmitting over a noisy channel. The authors present the results of polar code decoding simulation models testing using different algorithms that demonstrate the benefits of the proposed data processing method under conditions of low signal-to-noise ratios compared to canonical schemes required for redundant code decoding.

Energy Efficient Terminal Control of the Direct Current Servomotor 39_4.pdf

An optimal (on consumed power) segment length of terminal control of servodrive with a DC motor with zero initial and finite speed is determines. The optimal segment length of terminal control is related to the angular load displacement and the joint inertia. A new calculation formula for the optimal period of terminal control. The dependence of power consumption on the terminal control segment length is investigated.It has a unique minimum at given initial and final conditions and given characteristics of the servodrive. The formula is obtained that allows to evaluate the minimum energy consumption in DC servomotor terminal control. The parameters of the formula are determined by the characteristics of the servodrive, initial and final conditions. The possibility of approximation of the control signal and the angular speed of the servodrive mechanical load in energy-efficient terminal control is demonstrated. The control signal corresponding to the DC servomotor energy-efficient terminal control can be approximated a linear function of the time. The formula is obtained, that allows to calculate the maximum angular speed at the load shaft in energy-efficient terminal control with the DC motor servodrive.A structure chart of the automated control system of the DC servomotor with the terminal control block is presented. Diagrams for the transient processes in energy-efficient terminal and line control of DC motor is plotted.

Error Estimation of Thermal Conditions of Measurement Trancdusers With Differential Connection of Sensors 39_13.pdf

The main sources of errors of transducers with sensors differential connections caused by the distinction of thermal conditions of the sensing elements work are considered. Expressions for the distinction of sensors temperature in static and dynamic modes of operation caused by both the distinction of sensors parameters heat and the power dissipated by sensors are obtained. It is shown that instant at grading of the converter with various thermal time constants of sensors the thermal nature error reaches a maximum at a particular instant depending on the relation of thermal time constants. The thermal nature error can also significantly exceed the error in steady conditions.Errors of the differential photodiode are estimated on the basis of obtained expressions, and it is shown that the error of thermal conditions has multiplicative character and depends on the sizes of a light spot. For converters of bridge type the zero temperature drift is proportional to a difference of sensing devices thermal resistance. The more the total thermal resistance of sensors is the more, the more the size of temperature imbalance is.

The Algorithm for the Frequency-dependent Thermal Impedance Parameter Identification of Thermal Circuits of the Semiconductor Devices 38_6.pdf

The limit functionality and reliability of semiconductor devices (SD) are determined by the active region temperature of the device structures when the SD is operating as a part of electronic equipment. For practical applications, this temperature is calculated in accordance with the principle of thermoelectric analogy based on the equivalent thermal circuit which is presented as an electric circuit of several series-connected RC-elements, each of which corresponds to a specific layer of the SD-structure. The effectiveness of the SD-assembly quality control and the reject of devices with heat sink defects depend on the accuracy of determining the parameters of their equivalent thermal circuit. A brief analysis of the known methods for identifying and determining the parameters of the SD equivalent thermal circuit over the transient thermal characteristics is presented. A more accurate algorithm for the identification and the calculation of the parameters of equivalent thermal circuits in the form of SD multilink RC circuit for the frequency dependence of the modulus and the phase of the thermal impedance is proposed. The algorithm approbation is performed in terms of the identification and the calculation of the parameters of the thermal model of a low-power hetero junction LED of the Vishay production TLCR5800 type. The possibilities of automation of the proposed algorithm in terms of mass control are considered.

Estimation of Hardware Processing Costs in a Method of Soft Algebraic Decoding of Non-binary Codes 37_6.pdf

The paper shows estimation of the implementation complexity for the algorithms of algebraic decoding of non-binary codes by giving an example of Reed-Solomon codes. Advantages of soft data processing methods over traditional models of decoders with error-correction are given. The introduced redundancy can be used at the asymptotic capability edge. The paper also suggests a suboptimal data processing algorithm to minimize the risk of decoding error. This algorithm uses a provocation method, which calls a predictable decoder reaction while correcting a deliberately erased symbol with the reliable index of soft decision. There is a significant gain in efficiency of signal-code processor in receiver due to reduction of hardware costs in computation of the error locator polynomial and its solving by regular method instead of fitting.

Spectral Method of Measurement of the Led Thermal Resistance and Estimation of the Optimal Performance 36_5.pdf

The computer simulation helped the authors in studying the kinetics of the LED heating by the pulse-width modulated power varying harmonically. The programming model relies on a principle of the thermoelectric analogy saying that the heat dissipation processes on the path “chip - substrate - case - radiator - environment” are similar to electrical processes in the equivalent circuit, which is a set of serial-connected RC-chains. The task of simulation was to validate the LED thermal resistance measurement method based on heating by PWM power, as well as to study the effect on the accuracy and sensitivity of the method parameters such as heating pulse repetition period, frequency, and modulation coefficient, the number of heating pulses per modulation period. The simulation results shows that the method has an accuracy of 3%, and this value is independent of the heating pulse repetition period ranging between 80-200 ms. Sensitivity of the method depends on the modulation frequency of the heating power and heating pulse repetition period. It decreases with increasing modulation frequency, increases with the decrease of the repetition period at constant amplitude of oscillation pulse duration.

Structural Ways to Improve the Quality of Recirculationvernierulse Time-digital Converters 35_13.pdf

The article examines a structural method for increasing twice the speed of the recirculation vernier pulse-time-to-digital converters (TDC) with two operating modes and discrete transformations given less than one nanosecond. In the first mode, the period of the start pulse recirculation is selected higher than the highest duration values of the converted time slot (TS). This mode consists of the fact that the start and the stop pulses of the converted TS are recycled in their respective start and stop recirculators recycling with the periods differing by the value of specified discrete transformations, and the fact that the stop pulse recirculation number is counted from the time it enters the stop-recirculator and until the time the recirculation start- and stop-pulses match. At this, each of the recirculations has the start pulse duration extended to a predetermined value of discrete transformations, and the stop pulse duration remains unchanged. In the second mode, the period of the start pulse recirculation is selected less than the highest duration values of the converted TS, and the whole conversion process is carried out in two stages. At the first stage, the number of recirculations is counted during the TS conversion having the readability equal to the period of the start-pulse recycling, while at the second stage, the number of the stop pulse recirculations is counted with given discrete transformations made from the time it enters the stop- recirculator and recirculated until the time matches the start and stop pulses, allowing you to identify the digital conversion result. And if, during the first stage of transformation recycle start- duration pulse remains unchanged, at the second stage, its duration is extended by the given value of discrete transformations in each of recycles. At the same time, the stop pulse duration remains unchanged in the recycling process. To improve the reliability of the recirculation vernier - conversion TDC pulse at the two modes, a method is provided, wherein the start pulse expansion operations are excluded in each of the recirculations, and the recycling period increases by the predetermined discrete transformation. The article gives examples for the hardware (circuit) implementation of the proposed methods and recommendations for their use.

Reachability Analysis Method of Digital Automata Logic Circuits Stable States 35_14.pdf

The method is based on representation of digital automata logic circuits in the form of Petri nets state equations of Murata equations class. The inhibitory Petri nets are used for the digital automata logic simulation. Inhibitory Petri nets provide the most accurate simulation of logic circuits but lose their basic properties at a rather high modeling capacities and have the lower capacity of resolution compared to classical Petri nets. The problem solving is achieved by the inhibitory Petri nets presentation as matrix equations with implicit specified inhibitory arcs in the incidence matrix. The Petri nets graphics is used as a transition tool from the initial description of the automata to its representation as an equation of Petri nets states or as a set of linear algebraic equations. The digital automata network model-building is performed on the base of a homogeneous data flow conservation. Homogeneity property of the network model provides preservation of the inhibitory Petri nets properties in the network model to simulate the logic and simultaneously serves as a criterion of stable states reachability. Reachability analysis of logic circuits stable states comes down to solving the equation of Petri nets states at the given reachability criteria. The method can be used for solving the basic structural circuit automata logic synthesis tasks, test generation, simulation, faults modeling and computation, fault-tolerance and reliability analysis of automata logic circuits.

An Algorithm to Determine a Set of Optimal Frequencies for the Test Signal When Measuring Parameters of Multielement Two-terminals 35_4.pdf

An algorithm for determining the optimal test signal frequency set, minimizing the sum of methodical errors indirect measurement of parameters of multi-element two-terminal by impedance spectroscopy method is proposed. The essence of the algorithm is repeated computer simulation of the measurement of the impedance modulus and phase of the two-pole considering additive random errors and calculation errors in determining the parameters of the two- terminal to the relevant functional dependencies on a given set of frequencies. The accuracy of the algorithm is confirmed by the example of the two-element two-terminal in the form of a parallel RC-circuit. It is shown that the results of computer simulations practically coincide with the results of the analytical calculation. An example of determining the optimal test signal frequency set when measuring the three-element two-terminal with a structure similar to small-signal equivalent circuit of a semiconductor diode. As optimization criterion adopted condition of minimum sum of relative errors in the determination of all parameters of multielement two-terminal, but the proposed algorithm works with the other criteria.

Computer System Resource Posttest Prediction 35_7.pdf

The article deals with problems of the computer system resource posttest prediction derived from accelerated tests under different influences. Resources estimation methods are divided into four groups: statistical, deterministic, physic-statistics, and expert methods. The first three are the most commonly used methods. The analytical methods for accounting of effect of these influences on resource were made only for individual factors, while not always taken into account particulars of random influences. The methods of calculating the service life related with the fatigue strength are known. There were analyzed external influences that have the greatest impact on the design of the device so that to develop an effective method for estimating the resource. On the basis of analysis and accelerated testing, the method of estimating the mean and gamma-percentile resource based on the distribution of time to failure, the parameters of which are determined by calculation, has been proposed. The tests were carried out on a large group of modules for each selected action. There was given an example of calculation of the system as the serial communication subsystems, where each of subsystems is under the influence of the vibration, temperature, power supply ON and OFF.

The Formation of Relaxed Solutions in the System of the Broadband Channel With Qpsk–qam 33_11.pdf

A relevant problem of a soft-decision indexes (SDI) forming for non-binary codes consisted in the signal sets under its processing at the non-stationary channel output is settled. On the one hand, the increasing of positions in such sets leads to the system data rate rise, but on the other hand, it reduces the Euclidean distance between the points of signal constellation. Such contradiction is resolved by choosing a reasonable modulation rate in combination with the means of transmitter error-correction coding and soft code pattern decoding by the receiver with SDI.
