Abstract: A receiver is disclosed that includes a slicer having an input to receive a sequence of symbols exhibiting inter-symbol-interference (ISI). The slicer determines a state associated with each symbol based on a threshold. A feedback equalization unit is coupled to the slicer to apply equalization to the symbol fed to the slicer input based on prior detected symbol states. A Least-Mean-Square (LMS) unit cooperates with the slicer and feedback equalization unit to estimate a channel impulse response based on the equalized symbols. The LMS unit feeds the estimated channel impulse response to a Maximum-Likelihood-Sequence-Estimation (MLSE) unit to generate an estimated sequence of bits based on the estimated channel impulse response.
