Abstract:

Research of the BER performance of multifrequency PSK-4 signals with nonorthogonal location of subcarriers has been conducted. Elementwise coherent detection algorithm with compensation for interchannel interference (and multistep modification) and algorithm according to the state diagram are proposed.
