Due to the heavy computational complexity existing in the ESPRIT algorithm of rapidly time variant fading channels prediction, an algorithm for channels prediction based on the double smoothing technique and reassembling the covariance matrix is given. Through the theoretical analysis and simulation, it has been indicated that the modified algorithm can reduce dimensions of the covariance matrix and decrease the computational complexity. Meanwhile it can reduce the mean-square error of channels’ prediction coefficient.
