A Cyclostationarity-Based Approach to Blind Channel Identification for an OFDM System
基于OFDM信号周期平稳特性的盲信道估计算法

An approach, which exploits the cyclostationarity of the received signal, to blind channel identification for an OFDM system in frequency selective channel is presented in this paper. First, by utilizing the power distribution of the cyclic autocorrelation function of the received signal, the order of the channel is achieved. Then, the estimated channel is got by identifying its zeros. Finally, simulation results are provided to show that it is superior to the other algorithms.
