摘要
The Letter shows that the decision feedback multiple-symbol differential detection (DF-DD) schemes proposed by Leib and Pasupathy [2] and by Edbauer [3] are equivalent, and that DF-DD is an approximate realisation of maximum likelihood differential detection (ML-DD) proposed by Divsalar and Simon [1]. A theoretical BER analysis shows that DF-DD can achieve a BER performance almost the same as ML-DD.
