同时

对该方案进行了优化。仿真表明

当M次幂算法与DAML算法参数均取最优值时

冷启动方案性能达到最佳。

Abstract

The optical coherent receiver with Data-Aided Maximum Likelihood（DAML）carrier phase estimation has become one of the coherent reception modes to be considered for tests in the optical communication field in the near future.This paper studies the initiation of this type of receiver and on this basis proposes a cold-start scheme.Simulation verify the feasibility of this scheme.Furthermore it optimizes this scheme and simulation results show that when both the parameters of the Mth power algorithm and the DAML algorithm take the optimal values

the cold-start scheme achieves the best performance.
