Patent ID: 8743932

Claim:
A discrete multitone transceiver (DMT) comprising: a deinterleaver configured to de-interleave a plurality of bits; a forward error correction decoder configured to decode the plurality of bits; an impulse noise length determination module configured to determine, during Showtime, an impulse noise protection value, wherein the impulse protection value specifies a number corrupted DMT symbols correctable by the forward error correction decoder in combination with the deinterleaver; and a receiver, including the deinterleaver and the forward error correction decoder, configured to: receive using a first interleaver parameter value; receive a flag signal; and change to receiving using a second interleaver parameter value that is different than the first interleaver parameter value, wherein the second interleaver parameter value is used for reception on a pre-defined forward error correction codeword boundary following reception of the flag signal.
