Abstract
A method and apparatus for decoding a corrupted code word is described. Decoding is accomplished by using a decoder that has a common measure of reliability for each symbol of the corrupted code word and determining whether a useful result can be obtained from the first decoder. If a useful result can not be obtained decoding the corrupted code word is accomplished with a second decoder that uses unique values of reliability for each symbol of the corrupted code word.
