Patent ID: 7796705

Claim:
In a Discrete Multi-Tone (DMT) transceiver, a method of improving initialization in the presence of impulse noise comprising: transmitting or receiving, during an initialization procedure of the DMT transceiver, wherein the initialization procedure occurs prior to Showtime, a first initialization message indicating an Impulse Noise Protection (INP) value, wherein the INP value is used for DMT symbols transmitted during Showtime and the INP value specifies a number of consecutive DMT symbols that, when completely corrupted by impulse noise, can be corrected; and transmitting, during the initialization procedure of the DMT transceiver, wherein the initialization procedure occurs prior to Showtime, a second initialization message by modulating at least one message bit of the second initialization message onto a DMT symbol and repeatedly transmitting the DMT symbol N times, wherein N=A*INP+B, where A and B are integers and INP is the impulse noise protection value.
