Abstract

An equalizer includes: a channel estimator configured to generate a set of time-domain channel coefficients based on a receive signal; a frequency-domain transformer configured to generate a set of frequency-domain channel coefficients based on a frequency transform of the set of time-domain channel coefficients; an equalizer coefficient generator configured to generate a set of frequency-domain equalizer coefficients based on the set of frequency-domain channel coefficients; a time-domain transformer configured to generate a set of time-domain equalizer coefficients based on a time transform of the set of frequency-domain equalizer coefficients; and a filter configured to filter the receive signal based on a filter function that is based on the set of time-domain equalizer coefficients.
