ABSTRACT:
A frequency-domain-equalization apparatus for a receiver in single-carrier communication comprising: a selection means (103) for selecting a time-sequence-signal portion from a received signal that is longer than one block; a Fourier-transformation means (104) for performing Fourier transformation of the time-sequence-signal portion that is longer than one block and converting the signal to a frequency-domain signal; a channel-compensation means (105to106) for estimating the channels in the frequency domain and performing channel compensation, and a selection means (107, 108; 151) for performing inverse-Fourier transformation of the channel-compensated signal and selecting a one-block time-sequence-signal portion from the inverse Fourier-transformation results.
