Method and apparatus for equalization and crosstalk mitigation

Claimed is a method and apparatus for eliminating noise in multi-channel communication system. In one embodiment, the system is configured for use in information erasing on the channels receiving, and receiving to harass FEXT on channel. To generate FEXT erasure signal, and from the other wave filter device of receiver, the process for example, FFE and DFE wave filter device for acquiring. Therefore, wherein the wave filter device undertook apparatuses the process burden a part, which can make that the FEXT erasure signal is a generate heat complex degrees lowered. In a structurally, coding FEXT capable of a pre-formed, coding FEXT wave filter device corresponding one or more to coding FEXT erasure signal in each generates of the channels for pre-twisted patching bar is pre-formed. The coding FEXT erasure signal and is wrapped and related to the transmission in advance of each signal of the notches is combined, wherein eliminated FEXT front transmission a pre-formed.
