Abstract :
In order to solve the phase rotating problem in constant modulus algorithm (CMA) for polarization division multiplexing system with optical coherent receivers, we propose a modified CMA to simultaneously accomplish joint blind equalization, polarization de-multiplexing and phase recovery.
