Abstract
A modem receiver has an equalizer which receives an input signal, an adaptive compensator, and a decision block which generates a decision related to the input signal. A difference between an output of the equalizer and a compensating signal output of the adaptive compensator provides an input for the decision block. A difference between the output of the equalizer and an output of the decision block provides an error estimation signal which is a first input to the adaptive compensator. A difference between the input to the decision block and the output of the decision block provides an error adaptation signal which is a second input to the adaptive compensator.
