Abstract
A method and apparatus decodes a data packet in a communication system utilizing an error correcting code. Channel symbols are received (302), and channel symbol reliability weights are determined (306) for each. A code word symbol is formed (308) from the channel symbols, and the channel symbol reliability weights are mapped (312) into a code word symbol reliability weight, which is set equal to the minimum channel symbol reliability weight mapped for the code word symbol. The method and apparatus continues (318) to similarly process additional channel symbols until the data packet is completely collected. Then, a predetermined number of code word symbols having the lowest code word symbol reliability weights in the data packet are marked (320) as erasures, after which the data packet is decoded (322) by utilizing a soft decision decoding technique.
