Abstract
Provided is an apparatus for estimating a delay spread of a multi-path fading channel in an Orthogonal Frequency Division Multiplexing (OFDM) system. The apparatus is applied to an OFDM receiver including a channel equalization unit compensating channel distortion by estimating channel distortion at pilot locations with respect to output signals of an FFT unit.
