Abstract
Impulsive noise is detected for each discrete multi-tone (DMT) symbol. If impulsive noise is detected, all bytes, which belong to the associated DMT symbol are tagged by “erasure bits”. After interleaving, Reed-Solomon decoding is initially performed without erasures. If the decoding fails, it is performed again, this time with erasures. Reed-Solomon decoders report failure with relatively high certainty, and thus, if the first stage (decoding without erasures) includes failure or errors due to impulsive noise, the second stage of decoding is performed again with erasures.
