Patent ID: 8472510

Claim:
A receiver, comprising: a time-domain equalizer, for equalizing a received signal to generate a first equalized time-domain signal; a discrete Fourier transform unit, for performing a discrete Fourier operation upon the received signal to generate a frequency-domain signal; a frequency-domain equalizer, coupled to the discrete Fourier transform unit, for equalizing the frequency-domain signal to generate a first equalized frequency-domain signal; an inverse discrete Fourier transform unit, coupled to the frequency-domain equalizer, for performing an inverse discrete Fourier transform operation upon the first equalized frequency-domain signal to generate a second equalized time-domain signal; and an output circuit, coupled to the inverse discrete Fourier transform unit and the time-domain equalizer, for generating a third equalizing time-domain signal according to the first equalized time-domain signal and the second equalized time-domain signal; wherein at least a portion of tap coefficients of the time-domain equalizer are updated in every symbol, and a portion of tap coefficients of the frequency-domain equalizer are updated every plurality of symbols.
