SYSTEM AND METHOD FOR GENERATING SOFT DECISION RELIABILITY INFORMATION FROM HARD DECISIONS IN AN OPTICAL SIGNAL RECEIVER

摘要

A system and method for generating soft decision reliability information from hard decisions in an optical signal receiver. The receiver may include a digital signal processor including a symbol reliability function for generating symbol reliability information associated with symbols encoded on optical signal. The symbol reliability information may be generated as a function of the symbols and hard decision outputs associated with the symbols.
