Abstract
An OFDM (orthogonal frequency division multiplexing) receiver is equalized by dividing each of a plurality of received OFDM symbols into a plurality of sub-symbols and outputting each of Fourier-converted signals corresponding to each of the sub-symbols, and estimating a channel response corresponding to each of the divided sub-symbols.
