Abstract: A decision-feedback equalizer (DFE) receives an incoming data stream and provides a stream of bit data outputs, and comprises a number of comparators (35) for performing a comparison of an input data sample (xn) with a number of pre-determined threshold values stored in memory (33), at least one correction block (37) for receiving the comparison result of a respective one of the comparators (35) and for generating a plurality of intermediate results corrected based on the sign of the comparison result, and a multiplexer (32) for selecting from the set of intermediate results depending on the output data history (31) to provide the stream of bit data outputs.
