摘要：
The leakage of channel impulse response (CIR) in the time domain channel estimation for a practical OFDM system is analyzed. A novel channel estimation algorithm is proposed, using the polynomial cancellation coding (PCC) training symbols and the frequency domain windowing to reduce the effect of CIR leakage. Comparison has been done between the proposed algorithm and the existing time domain channel estimation algorithms in the non-sample-spaced multipath fading channel. Simulation results show the remarkable decreasing of channel estimation MSE by the proposed algorithm.
