<p>The invention provides a method and device for correcting frequency offset. Through the response of all the pilot carrier for every tilestrip in every sub-channel, the corresponding matrix is Constructed, and the constructed matrix is normalized, and the average of the normalized matrix of every antenna is determined, thus the average of the normalized matrix of every received antenna for the base station is determined, and the Fast Fourier Transform (FFT) is proceeded according to it, thereby the estimation of the frequency offset is proceeded, then the frequency offset is corrected according to the result of the estimation of the frequency offset. Consequently the estimation and correction of the frequency offset is realized in the Orthogonal Frequency Division Multiplexing (OFDM) system.</p> |
