Abstract

A decision-feedback detection technique for MPSK is presented, which uses the previously detected symbols to estimate the initial phase in the current symbol for optimal coherent detection. The theoretical and simulated error performance results for uncoded MPSK are given. It is shown that the error performance of the DF detection is very close to that of ideal coherent detection with differential encoding/encoding which is used to overcome the phase ambiguities. The applications of the DF detection to convolutionally encoded QPSK is given
