Claim Text:
1. A method of processing in a receiver a signal that has been encoded and interleaved in a transmitter comprising: receiving the signal; process the signal to obtain a stream of soft metrics representing bit probability of symbols in a predetermined constellation, wherein the stream of the soft metrics are divided into a plurality of groups of the soft metrics; applying to the groups of the soft metrics a compression operation that preserves a total length of the groups of soft metrics, wherein the groups of the soft metrics are related to a same constellation symbol; and rearranging the stream of compressed soft metrics so as to inverse the interleaving done in the transmitter, wherein the compression operation generates a plurality of compressed codes, and the method further comprises a step of substitution of the compressed codes with other codes of shorter length representing a different symbol in the predetermined constellation when the total length of the groups of the soft metrics exceeds a determined value.
