Systems and methods for compensating for impulse noise

摘要

Embodiments of the present disclosure generally pertain to systems and methods for compensating for impulse noise. A system in accordance with an exemplary embodiment of the present disclosure comprises a receiver coupled to a subscriber line. The receiver is configured to receive an encoded data signal via the subscriber line and separate the signal into a common mode (CM) signal and a differential mode (DM) signal. The receiver is further configured to detect impulse noise on the CM signal and mark corresponding sub-words of the DM signal affected by the detected impulse noise as erasures. The receiver then decodes the DM signal based on whether the sub-words are marked as erasures.

1. A receiver for compensating for impulse noise, comprising:
a signal component sampling element configured to receive a data signal from a subscriber line and to separate the data signal into a common mode signal and a differential mode signal; an impulse noise detector configured to detect impulse noise in the common mode signal; an erasure marking element configured to mark a sub-word of the differential mode signal as an erasure based on a detection of impulse noise in the common mode signal by the impulse noise detector, wherein the impulse noise detector is configured to compare the common mode signal to a threshold and to detect an occurrence of impulse noise based on a comparison of the common mode signal to the threshold, and wherein the impulse noise detector is configured to adaptively update the threshold; and a decoder configured to decode the differential mode signal based on whether the sub-word is marked as an erasure by the erasure marking element.
