Abstract

Differential detection based on MLSE using the Viterbi algorithm (Viterbi-decoding DD) is proposed and the BER performance of 2DPSK under AWGN channels is investigated by computer simulation. It is shown that the performance loss in the required E_bN₀ of the proposed Viterbi-decoding DD compared with ideal coherent detection with differential decoding is only around 0.15 dB at BER = 10^-3.
