Electrical estimation of conditional probability for maximum-likelihood based PMD mitigation
Wenze Xi, Tülay Adalı, John W. Zweck · Optical Fiber Communication Conference · 2005
Accurate probability density functions in the presence of both all-order PMD and ASE noise are estimated electronically, and used for maximum likelihood sequence estimation and a maximum a posteriori detection to mitigate PMD in the presence of ASE noise.
