Abstract
Impulse and/or burst noise signal to noise ratio (SNR) aware concatenated forward error correction (FEC). Adaptive processing is performed on a signal based on one or more effects which may deleteriously modify a signal. For example, based on a modification of a signal to noise ratio (SNR) associated with one or more impulse or burst noise events, which may be estimated, different respective processing may be performed selectively to differently affected bits associated with the signal. For example, two respective SNRs may be employed: a first SNR for one or more first bits, and a second SNR for one or more second bits. For example, as an impulse or burst noise event may affect different respective bits of a codeword differently, and adaptive processing may be made such that different respective bits of the codeword may be handled differently.
