Postdetection diversity that uses L differential phase detector outputs for data decision is described for Mary differential phase siiift keying (Mary DPSK). Data decision is based on minimising the weighted sum of the errors of L DPD detector outputs. The squared geometric mean of the two consecutively received signal envelope samples is used as the branch weight. The simulation results on average bit error rate (BER) performances due to additive white Gaussian noise (AWGN), multipath Doppler spread, and delay spread of π/4-shift 4DPSK are reported.
