Apparatus and method for synchronizing symbol timing synchronization applicable to orthogonal frequency division multiplexing (OFDM) receiver
An apparatus and method applied to an orthogonal frequency division multiplexing (OFDM) receiver performs symbol timing synchronization by correlation between channel impulse responses. The apparatus applicable to the OFDM receiver, includes a channel impulse response (CIR) estimator for estimating a CIR of a present symbol from which a symbol timing is to be detected, using a previous symbol received prior to the present symbol; a matched filter for computing the CIR using the present symbol; a correlation calculator for calculating correlation between the estimated CIR and the CIR computed at the matched filter; and a peak detector for detecting the symbol timing by obtaining a timing offset between the estimated CIR and the computed CIR based on a maximum value of the calculated correlation.
