Polarization Change Monitor Based on Jointly Applied Constant Modulus Algorithm and Carrier Phase Recovery in Coherent Receiver

The coefficient of adaptive equalizer could monitor the channel response, such as fiber link polarization change. We experimentally shown that the estimated carrier phase should also be included, if the equalizer uses constant modulus algorithm.
