N2 - This paper proposes an efficient and reliable blind channel estimation method for single transmitter and receiver antenna orthogonal frequency division multiplexing (OFDM) system. The proposed blind channel estimation method is based on the interesting cross-correlation property of the repeated structure of cyclic prefix (CP) in an OFDM symbol. Our cross-correlation based method, which utilizes the only information in CP, not entire symbol, is robust to additive white noise and not affected from the presence of null channel coefficients. Toeplitz structure induced in the cross-correlation matrix allows us a simple and reliable method for extracting channel impulse response effectively. In the simulation study, proposed method is compared with auto-correlation based approach and it demonstrate the superior performance of the proposed method.
