Adaptive decoding based on signal to noise ratio (SNR)

A communication device comprising:

• a communication interface configured to receive from another communication device a signal based on orthogonal frequency division multiplexing (OFDM) from a communication channel affected by noise;
• and
• a processor configured to:
• process the signal to generate a plurality of log-likelihood ratios (LLRs);
• scale one or more LLRs of the plurality of LLRs associated with one or more OFDM sub-carriers that are affected by both background noise and burst noise using a first signal to noise ratio (SNR) to generate a first one or more scaled LLRs;
• scale one or more LLRs of the plurality of LLRs associated with one or more OFDM sub-carriers that are unaffected by the burst noise using a second SNR that is based on the background noise to generate a second one or more scaled LLRs;
• and
• decode the signal using the first and the second one or more scaled LLRs and any LLRs of the plurality LLRs associated with one or more OFDM sub-carriers that is unaffected by the noise to make one or more estimates of one or more information bits encoded within the signal.

A method for execution by a communication device, the method comprising:

• via a communication interface of the communication device, receiving a signal that is formatted in accordance with orthogonal frequency division multiplexing (OFDM);
• processing the signal to generate a plurality of log-likelihood ratios (LLRs);
• scaling one or more LLRs of the plurality of LLRs associated with one or more OFDM sub-carriers that are adversely affected by noise using a background noise based signal to noise ratio (SNR) and a second burst noise based SNR to generate one or more scaled LLRs;
• and
• decoding the signal using the one or more scaled LLRs and any LLRs of the plurality LLRs associated with one or more OFDM sub-carriers that is unaffected by the noise to make one or more estimates of one or more information bits within that signal that are transmitted via the one or more OFDM sub-carriers that are adversely affected by the noise.
