A new cyclostationarity-based approach to blind channel identification for OFDM system

A new cyclostationarity-based approach to blind channel identification for OFDM system in frequency selective and slowly-varying channel is presented in this paper. Although it also exploits the cyclostationarity of the received signal, much improvement has been made, which includes the adaptability to the faster-varying channel, the ability to achieve the order of the channel and the smaller MSE of the estimated channel. Simulations show that the proposed algorithm is superior to the one reported early.
