METHOD AND APPARATUS FOR CHANNEL EQUALIZATION IN MULTI-CARRIER COMMUNICATION DEVICES USING DISCRETE COSINE MODULATED FILTER BANK OR WAVELET PACKET MODULATION

摘要

A method for channel equalization in a data communication system comprising at least two cosine modulated filter bank-based multi-carrier communication devices or at least two wavelet packet modulation-based multi-carrier communication devices being connected over a single transmission channel (103), the channel equalization being a recursive time-domain equalization comprising a finite impulse response equalization part (301) and an infinite impulse response equalization part (304, 304'), as well as an apparatus for channel equalization for use in one or more cosine modulated filter bank-based multi-carrier communication devices or in one or more wavelet packet modulation-based multi-carrier communication devices, the apparatus being a recursive time-domain channel equalizer (207) comprising a finite impulse response part (301) and an infinite impulse response part (304, 304').
