摘要:	In this paper, based on the correlation properties of the pseudo-random (PN) code, a scheme is proposed to achieve frame synchronization in the OFDM system. According to the estimated path delay time, the channel impulse response could be obtained with the proposed scheme. Then, based on the estimated channel response, the signal could be compensated through the one-tap frequency domain equalizer. Simulation results of the proposed frame synchronization scheme and channel estimation are presented in the paper. The miss probability of frame timing with the proposed frame synchronization scheme performs better than that with the moving average scheme and Beek's scheme. Besides, in the channel estimation, the estimator mean square error with the proposed algorithm is better than that with the algorithm using frequency domain pilots. Moreover, with the signal compensation by the estimated channel information, the frequency domain one-tap equalizer is used to improve the system performance. ? 2009 Elsevier Inc.
