Description: In this paper, the soft input soft output channel decoder output log-likelihood ratio with the variation of the phase error signal to noise ratio MPSK signals with low phase error cost function and propose a cost function for solving the iterative phase of the search method relatively less computation to achieve high accuracy phase estimates. Simulation results show that the algorithm is stable under low signal to noise ratio performance, and most of the phase estimation algorithm can overcome the phase ambiguity exists.
