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.
