Abstract
Embodiments of methods and apparatuses for gating impulse noise in a communication system are described. In one embodiment, a quality measure of a received signal on a communication channel is not adjusted when corruption by impulse noise in the received signal is detected. In another embodiment, tuning parameters of a DSL modem are not adjusted when corruption by impulse noise in the received signal is detected.

13. An apparatus, comprising:
a multi-carrier transceiver to detect data in a multi-carrier signal, the transceiver comprising;
a detector module to detect impulse noise in a tone of the multi-carrier signal, and a measurement and adaptation module coupled to the detector module to determine a quality measure of the multi-carrier signal, wherein the detector module prevents an adjustment of the quality measure by the measurement and adaptation module upon detecting corruption by impulse noise. - View Dependent Claims (14, 15, 16, 17, 18)
