N2 - With the development of the satellite communication, the relative velocity between the terminals is higher and caused larger the doppler shifting than traditional communication. In view of the above situation, we propose a algorithm which padding zeros in received signal in time-domain, then use energy sorting to eliminate severals of largest component in frequency domain channel estimation, and adopt doppler shift to further revised the channel parameter estimation. Computer simulation demonstrates that the proposed algorithm clearly outperform the conventional method of channel estimation, and the performance of Symbol Error Ratio(SNR) is improved at the larger doppler shifting.
