Abstract
An apparatus for estimating a timing offset of each of orthogonal frequency division multiplexing (OFDM) symbols that are fast Fourier transform (FFT)-processed. A first correlator calculates correlation values and outputs a first correlation signal. A second correlator calculates correlation values and outputs a second correlation signal. A third correlator calculates a correlation value and outputs a third correlation signal. A delay correlator calculates a correlation value and outputs a timing offset information signal. A phase estimator detects phase components of the timing offset information signal and a sliding integrator accumulates the detected phase components of the timing offset information signal during a symbol interval and outputs an average value of the accumulated phase components during the symbol interval as the timing offset of each OFDM symbol.
