METHOD FOR GENERATING SOFT DECISION SIGNAL FROM HARD DECISION SIGNAL IN A RECEIVER SYSTEM

A receiver system, which generates a soft decision signal from a hard decision signal, includes a hard output receiver for determining a received bit to generate a hard decision signal. A hard input soft output receiver determines an estimated probability of symbol data corresponding to the received...

Zusammenfassung:A receiver system, which generates a soft decision signal from a hard decision signal, includes a hard output receiver for determining a received bit to generate a hard decision signal. A hard input soft output receiver determines an estimated probability of symbol data corresponding to the received bit based on the hard decision signal and generates a soft decision signal represented by a log-likelihood ratio from the estimated probability.
