Abstract

We propose a new low-complexity strategy for approaching the matched filter bound on most practical ISI channels. At the transmitter, a form of channel-independent precoding is introduced to perform frequency-interleaving, which appropriately conditions the channel. At the receiver, a very low-complexity iterated-decision equalizer (Chan, A.M. and Wornell, G.W., IEEE Trans. Commun., vol.49, p.1966-76, 2001) is used. As an illustration, we use the system to attain the matched filter bound effectively on the 1+D channel without the use of error-control coding.
