Mohamad, Hafizal and Weiss, S. and Rupp, M. and Hanzo, L. (2001) A fast converging fractionally spaced equaliser. In: Thirty-Fifth Asilomar Conference on Signals, Systems and Computers, 2001-11-04 - 2001-11-07, Pacific Grove, CA.
We present subband adaptive structures that can counteract the slow convergence which is imposed on the feed-forward part of a fractionally spaced equaliser by the spectral dynamics of the oversampled channel output. While the prewhitening of the subband approach is therefore beneficial to the feed-forward part, additionally operating the feedback part in subbands results in a more balanced and faster convergence, which is demonstrated in simulations.
