Abstract:
An orthogonal frequency division multiplexing (OFDM) receiver capable of improving equalization performance is provided. In the OFDM receiver receiving an OFDM signal having a frame structure constructed with one reference symbol and a plurality of data symbols following the reference symbol, the OFDM receiver includes: a synchronizer which detects a position of the reference symbol from the received OFDM signal; a time-domain equalizer which equalizes in a time domain the data symbols that are separated by a distance longer than a predetermined distance from the position of the reference symbol; an FFT (fast Fourier transform) unit which performs an FFT process on the OFDM signal; and a frequency-domain equalizer which equalizes in a frequency domain the data symbols that are separated by a distance shorter than a predetermined distance from the position of the reference symbol.
