Abstract

In this article it is shown the expression defining the algorithm for the optical treatment of received signals and it can be obtained by means of the methods of statistical receiving and transmitting information theory and then it is made the selection of the structural scheme of optimal discrete signal reception of the optical range modulated by frequency or intensity in appropriate calculate technique of the verisimilitude relationship. There are the computations results and the probability detection using the analytical expressions of performance characterizing the detect process and receiving of the useful signals as well as the computations results in the threshold level.
