Performance of an adaptive rate modem using quasi-analytic simulation techniques

Analysis of bit error rate (BER) of a /spl pi//M-MDPSK modem in an (additive white Gaussian noise) AWGN channel using quasi-analytic simulation techniques is considered in this paper. Implementation losses, most notable at M=32 and 64, which result from practical transmit and receive filtering, can be largely overcome by increased accuracy symbol timing recovery and a fixed equalization filter.
