Abstract: An equalizer circuit including a filter, equalization circuitry, and a filter adaptation circuit. The filter is configured to produce a linearized signal based at least in part on a received input signal and a nonlinear transfer function. The equalization circuitry is configured to filter inter-symbol interference (ISI) and detect one or more data symbols in the linearized signal. The equalization circuitry is further configured to produce an error signal indicating an amount of error in the detected data symbols. The filter adaptation circuit is configured to dynamically adjust the nonlinear transfer function of the filter based at least in part on the error signal from the equalization circuitry.
