Application of corrected decision feedback differential detection algorithm for the detection of MDPSK signal

In this paper, decision-feedback differential detection with correction of M-ary differential phase shift keying (MDPSK) signals is proposed. Proposed scheme is compared with classic decision feedback differential detection (DF-DD) receiver. Results show that the proposed receiver has better performances in the presence of frequency offset, in a very wide range of frequency offsets. The proposed receiver is not much more complex than the ordinary DF-DD receiver since only one more complex multiplication was introduced.
