Abstract

The algorithm of time-frequency matrices signal recepts with pseudorandom operation frequency tuning communication is presented. The methodology of erratic symbol probability evaluation for channel constant parameters and for Rayleigh fading channel is given. The article presents also evaluation examples by different volumes of signals alphabet and quantity of transmitting elements symbols.
