Abstract

The results of imitational simulation of detection OQPSK and 8PSK signals in wireless channel with low signal-to-noise ratio are given in this paper. The simulation was maintained using Matlab program. The main goal of experiment is to confirm the efficiency of modified phase detector, in which specific combination of narrowband filters was used. The results of comparing quality indexes of modified detector and classical detector were illustrated on BER-to-SNR diagrams.
