Impulse noise management
First Claim
1. 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.

Abstract
A discrete multitone transceiver (DMT) includes a deinterleaver operable to de-interleave a plurality of bits. The DMT further includes: a forward error correction decoder operable to decode the plurality of bits, a module operable to determine, during Showtime, an impulse noise protection value, wherein the impulse protection value specifies a number corrupted DMT symbols that can be corrected by the forward error correction decoder in combination with the deinterleaver, and a receiver coupled to the deinterleaver. The receiver receives using a first interleaver parameter value, receives a flag signal, and changes 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.
