Abstract
An adaptive equalizer comprises: a forward equalizer (FE) receiving a symbol stream to generate an FE output; a decision feedback equalizer (DFE) receiving a decision symbol stream to generate a DFE output; a first adder, coupled to the forward equalizer and the decision feedback equalizer, adding the FE and DFE outputs to generate an equalizer output; a first trellis decoder, coupled to the first adder, receiving the equalizer output to generate a trellis decoded stream by a trellis decoding process; and a compensator for compensating the equalizer output according to the decision symbol stream, the trellis decoded stream, and a coefficient vector stored in the decision feedback equalizer, to generate a compensated equalizer output.
