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.
Claims19
A method, comprising:
- determining a quality measure of a received signal on a communication channel;
- and
- preventing an adjustment of the quality measure upon detecting corruption by impulse noise in the received signal.
An article of manufacture, comprising:
- a machine-accessible medium storing instructions that, when executed by a machine, cause the machine to perform operations comprising:
- determining a quality measure of a received signal on a communication channel;
- and
- preventing adjustment of the quality measure upon detecting corruption by impulse noise in the received signal.
1 more element
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.
