摘要：
An equalizer (400) includes: a channel estimator (401) configured to generate a set of time-domain channel coefficients (402) based on a receive signal (202); a frequency-domain transformer (403) configured to generate a set of frequency-domain channel coefficients (404) based on a frequency transform of the set of time-domain channel coefficients (402); an equalizer coefficient generator (405) configured to generate a set of frequency-domain equalizer coefficients (406) based on the set of frequency-domain channel coefficients (404); a time-domain transformer (407) configured to generate a set of time-domain equalizer coefficients (408) based on a time transform of the set of frequency-domain equalizer coefficients (406); and a filter (411) configured to filter the receive signal (202) based on a filter function that is based on the set of time-domain equalizer coefficients (408).
