An Improved Method of PS-QPSK Based on Kmeans for Optical Systems

To mitigate nonlinear impairments in optical PS-QPSK transmission, Kmeans methods are proposed for signal decision. Numerical results show that Kmeans can effectively reduce the BER after 1600km transmission while little extra complexity increase.
