Abstract
A digital communication receiver generates soft decision values at the output of a maximum likelihood sequence estimator module. The values are fed into a following forward error correction module that uses the soft-decision input signal to improve error correction performance. The disclosed techniques can be used for receiving optical signals in an optical communication network.
