Abstract
An ISI cancellation equalizer is disclosed. The ISI cancellation equalizer comprises a non-linear mapping circuit, a filter, a delay circuit, and a combiner. The non-linear mapping circuit generates a mapped signal by mapping a level of an input signal into a predetermined value when the input signal falls in a predetermined region, and linearly maps the level of the input signal when the level of the input signal is beyond the predetermined region. The filter depresses an inter-symbol interference (ISI) in the mapped signal to generate a filtered signal. The delay circuit filters the high boosted signal to generate a delayed signal. The combiner combines the filtered signal and the delayed signal to obtain an equalized signal.
