Abstract:
This paper demonstrates a stochastic gradient descent four-parameter algorithm to achieve integrated compensation for RSOP and phase noise in coherent optical communication systems. The experimental results show superior advantages in ultra-fast RSOP tracking speed up to 20 Mrad/s and the elimination of singularity issues.
