Approaching the Matched-Filter Bound Using Iterated-Decision Equalization with Frequency-Interleaved Encoding

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 lowcomplexity iterated-decision equalizer [1] is used. As an illustration, we use the system to effectively attain the matched filter bound on the 1+D channel without the use of error-control coding
