Impulse and/or burst noise signal to noise ratio (SNR) aware concatenated forward error correction (FEC)

摘要

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.

1. A communication device comprising:
a communication interface; and a processor, at least one of the processor or the communication interface configured to:
receive a signal from another communication device via a communication channel;process the signal to generate a plurality of bits;process the bits to identity at least one bit of the plurality of bits that is affected by at least one of an impulse noise event or a burst noise event and at least one other bit of the plurality of bits that is unaffected by the at least one of the impulse noise event or the burst noise event; anddecode the signal to generate an estimate of an information bit encoded therein including to:
decode the at least one bit of the plurality of bits based on a first signal to noise ratio (SNR), wherein the first SNR is associated with the at least one of the impulse noise event or the burst noise event; anddecode the at least one other bit of the plurality of bits based on a second SNR that is different than the first SNR.
