A co-designed decision feedback equalizer, deinterleaver and decoder

A technique is presented that promises high-quality data from bandlimited channels at lower received power in digital transmission systems. Data transmission in such systems often suffers from intersymbol interference (ISI) and noise. Two separate techniques, channel coding and equalization, have produced considerable advances in the state of communication systems, and both concern themselves with removing the undesired effects of a communication channel. Equalizers mitigate the ISI, whereas coding schemes are used to incorporate error-correction. It is shown that an integrated approach realizes gains in excess of that of a simple juxtaposition
