We discuss the effects of abrupt channel variations on the performance of echo cancellation in a Power Line Communications (PLC) scenario. Our work takes into account field measures of high voltage PLC channels and considers an adaptive Least Mean Square (LMS) echo canceller in a full-duplex communication system. We investigate the LMS convergence speed, also in the presence of impulse noise, and propose a modified adaptive LMS algorithm in order to improve the performance in the presence of abrupt echo channel variations.

Abstract
We discuss the effects of abrupt channel variations on the performance of echo cancellation in a Power Line Communications (PLC) scenario. Our work takes into account field measures of high voltage PLC channels and considers an adaptive Least Mean Square (LMS) echo canceller in a full-duplex communication system. We investigate the LMS convergence speed, also in the presence of impulse noise, and propose a modified adaptive LMS algorithm in order to improve the performance in the presence of abrupt echo channel variations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
