An Alternate Bayesian Approach to the Detection of an Adaptive Decision Threshold Scheme for the Receiver At Decameter Radio Links 52_9.pdf

The article deals with an approach to the determination of the decision threshold scheme of a receiving device in decameter radio link, which implements the alternative Bayesian method. In contrast to the classical approach when the decision threshold scheme is determined with the assumption that the probability density function (PDF) of the received signal is subject to the Gaussian low, an approach based on the current recovery of instantaneous values of the received signal envelope in each distribution path is proposed. The PDF recovery algorithm is based on the nonparametric Parzen-Rosenblatt density estimation method. The estimating is carried out during a specified communication session. In this case, the most probable values of the signal (mode) are determined if the noise interference is absent and present, the decision threshold scheme is established in accordance with the real situation on the communication line. Then, on the basis of the mode shift, a decision is made about the signal-error probability. On the basis of simulation modeling, the efficiency of the approach is shown when operating at decameter radio links working under nonparametric prior uncertainty relative to signals and interference.
