Autonomous impulse noise mitigation in communication systems

摘要

The present invention relates to a communication system (10) comprising a first device (1) and a second device (2) exchanging signals over a transmission medium, the first device comprising a first processing part (12) for adjustably processing signals to be transmitted over the transmission medium towards the second device, and the second device comprising a second processing part (22) for adjustably processing signals received through the transmission medium from the first device,
the first device comprising an impulse noise measuring part (31) for measuring characteristics of impulse noise affecting signals received through the transmission medium from the second device. A communication system according to the invention further comprises an extrapolating part (32) for determining characteristics of impulse noise affecting signals transmitted over the transmission medium towards the second device based on measured impulse noise characteristics determined by the impulse noise measuring part,
and an adjusting part (33) for issuing adjustment signals destined for the first and second processing parts for adjusting their processing based on extrapolated impulse noise characteristics determined by the extrapolating part. The present invention also relates to a method for use in a communication system comprising a first device and a second device exchanging signals over a transmission medium, and related network and consumer device and computer program and medium.
