Abstract
An apparatus generally having a first circuit and a second circuit. The first circuit may be configured to (i) generate an equalizer parameter in response to an input signal, the equalizer parameter causing a cancellation of post-cursor inter-symbol interference from a plurality of symbols in the input signal and (ii) generate an output signal in response to both the input signal and the equalizer parameter. The second circuit may be configured to (i) generate a target parameter signal in response to the input signal, the target parameter signal representing a mean value of a plurality of sample points of the symbols and (ii) generate a control signal in response to the target parameter signal, the control signal causing a reduction of the equalizer parameter, the reduction causing a decrease in the cancellation of the post-cursor inter-symbol interference from the symbols, wherein the apparatus does not cancel pre-cursor inter-symbol interference.
