METHOD FOR HANDLING TRANSMISSION ERRORS ON A TELECOMMUNICATIONS TRANSMISSION LINE

摘要

When data retransmission is used to handle errors caused by impulse noise, buffer memory requirements may be reduced and/or data rate increased by detecting impulse noise at the transmitting equipment and initiating retransmission in response to such detection rather than waiting for a retransmission indication from the receiving end. The decision to retransmit may be made dependent on the strength or other properties of the detected noise burst. The decision criterion may be made adaptive by correlating noise burst properties with received retransmission indications or the absence thereof.
