Abstract :
A computationally efficient frequency domain implementation of a fractionally-spaced equalizer with inter-channel spectral alignment is proposed for inter-channel-crosstalk cancellation. The algorithm is an essential component of crosstalk cancellation and reduces the complexity without sacrificing performance.
