Abstract The method for implementing frame synchronization and equalization coefficient correction includes the following steps: equal-dividing whole channel into N subchannels according to frequency spectrum; making adaptive frequency domain equalization design for every subchannel and using W(k) as frequency domain equalization coefficient of K subchannel; extracting phase deviation information from frequency domain equalization coefficients of all the subchannels; making angular phase difference separation treatment and driving them into angular phase difference resulted from integral sample points in synchronous symbolic frame and resulted from integral sample points in synchronous symbolic frame and residual angular phase difference, according to integral sample point values making synchronous symbolic frame shift correction, and designing rotation factor according to residual angular phase difference and making rotation correction for frequency domain equalization coefficient.
