Stochastic BER estimation for coherent QPSK transmission systems with digital carrier phase recovery.

Abstract

We propose a stochastic bit error ratio estimation approach based on a statistical analysis of the retrieved signal phase for coherent optical QPSK systems with digital carrier phase recovery. A family of the generalized exponential function is applied to fit the probability density function of the signal samples. The method provides reasonable performance… (More)
