Abstract

For 112 Gb/s polarization-multiplexed quadrature-phase-shift-keying systems, the generalized Gaussian probability density function is used to quantify the impact of carrier phase estimation algorithms on the statistical properties of the resultant signal sample values and to obtain an estimate of the system bit error ratio when direct bit error counting is not feasible. The shape parameter in the probability density function is useful for distinguishing the performance of different signal processing algorithms and system configurations.
