For VDSL systems, alien noise cancellation using an additional common mode sensor at the customer premises equipment (CPE) receiver can be done by combining the differential-mode (DM) signal with the common-mode (CM) signal passed through a long linear filter. Frequency domain per-tone cancellation offers a low complexity approach to the problem but suffers from loss in cancellation performance due...
Impulse noise cancellation using an additional common mode sensor at the customer premises equipment (CPE) receiver is akin to an interference cancellation problem in a SIMO receiver. However, the common mode (CM)-differential mode (DM) cross-correlation for impulse noise signal needs to be estimated during showtime in the presence of a much stronger DM useful data signal. Existing works on this topic...
