Polarization de-multiplexing based on T-CMN

In order to mitigate the crosstalk in polarization multiplexing (PM) systems and achieve more effective performance of de-multiplexing, the fixed-point algorithm based on complex maximization of negentropy (T-CMN) is presented for the first time to implement polarization de-multiplexing in a 2×2 PM system. The algorithm successfully implements de-multiplexing, furthermore some very properties of the T-CMN, such as strong robustness, inverse-free of the matrix and transparent to the modulation format, make it more suitable for polarization de-multiplexing.
