Abstract:
1. An integrated circuit communication device comprising: a multi-state decoder operable to receive a multi-state representation signal and to generate tentative decisions and a final decision based on the received multi-state representation signal; a single-state decision feedback equalizer operable to receive at least one tentative decision from the multi-state decoder, the at least one tentative decision corresponding to a single state of the multi-state decoder, and operable to generate a single-state intersymbol interference (ISI) compensation signal based on the at least one tentative decision; a combiner operable to combine the single-state ISI compensation signal with an input signal to produce a single-state representation signal; and a state multiplication circuit operable to expand the single-state representation signal received from the combiner into a multi-state representation signal suitable for decoding by the multi-state decoder.
