Paper Abstract

In order to solve the phase rotating problem for constant modulus algorithm (CMA) in polarization division multiplexing system with optical coherent receivers, a modified constant modulus algorithm based on decomposing cost function into real and imaginary parts is proposed in this paper. Simulation results show that, the proposed algorithm can compensate any angle phase distortion arising from channel, and deal with phase offset caused by intradyne receiver, with better performance comparing the conventional CMA.
