Description: Perfect OFDM procedures, according to the characteristics of the short training word correlation operation, the signal reaching the detector, when the detected correlation value is greater than a certain threshold number of times that the signal arrives. Then according to the characteristics of the long training words, the correlation operation, to estimate the OFDM symbol FFT window starting position. The estimated position of the FFT window, the first in the time domain frequency offset estimate small, two small words long training frequency offset compensation after FFT operation, estimated integer frequency offset based on the result of the FFT operation. These parameter estimation is completed, the data can be demodulated. The first portion of the data of the complete frequency offset compensation, and then performs the FFT operation to obtain data in the frequency domain, demodulates the estimated FFT window position. Then extract the subcarrier corresponding to the pilot positio
