Design of FIR filterbank transceivers with effective band separation

The DMT (discrete multitone modulation) transceivers have been shown to be a very useful technique for data transmission over frequency selective channels. The DMT scheme is realized by a transceiver that divides the channel into subbands. The efficiency of the scheme depends on the frequency selectivity of the tranceiving filters. The filterbank transceiver or DWMT (discrete wavelet multitone) system, has been proposed as an implementation of DMT transceiver that has better frequency band separation. In this paper, we show how to design filterbank transceivers that have good frequency selectivity and at the same time cancel ISI completely.
