Decoding system and method for digital communications

A method of applying a plurality of weights used for decoding a respective plurality of signals within a respective plurality of frequency bins, the method comprising the steps of:

• determining a weight for each of the respective plurality of signals within the respective plurality of frequency bins based in part on a channel estimate;
• and
• in a wireless receiver, applying each weight to bit metrics associated with one of the respective plurality of signals during a Viterbi decoding process, wherein the at least one of the weights applied is unity.

A method of determining a plurality of weights used for decoding a respective plurality of signals within a respective plurality of frequency bins, the method comprising the steps of:

• determining a weight for each of the respective plurality of signals within the respective plurality of frequency bins based in part on feedback received from previously decoded signals;
• and
• in a wireless receiver, applying each weight to bit metrics associated with one of the respective plurality of signals during a Viterbi decoding process.
