Using Adaptive Filtering of Signals for Estimation of the Mahalanobis Distance

This article focuses on estimating the Mahalanobis distance when there is a dual channel receiving a binary signal. The greatest probability value P-np-adequate signal reception-corresponds to the largest Mahalanobis distance, that is, the optimal tuning of an interference filter. The importance of estimating P-np results from the size of a controlled zone necessary to secure the information being processed: it is found in spurious radiation and regulated by the recommendations of the FSTEK agency, Russia. In contrast to earlier works, proposed algorithms of estimating the value of P-np do not use any information about a learning binary reference sequence. Two types of algorithms are considered for dual channel receiving mode: moving estimates and the Widrow-Hoff stochastic gradient descent.
