On the performance of single-channel blind separation of two co-frequency MPSK signals

Single-chsmnel blind separation of two co-frequency multiphase phase-shift keying (MPSK) signals has proved to be practically feasible. In this paper, we investigate the performance of symbol detection. An upper bound of symbol error rate (SER) is derived in a closed form using Forney's method and its properties are studied analytically and through computer simulations.
