Abstract
In this paper, we provide a new algorithm and a mathematical model of channel estimation, which are based on pseudo-random code and all-phase FFT in OFDM system. The Matlab simulations in the Channel Rayleigh and Channel Rician show that it can accurately estimate the change of channel very well in the fast time-varying channel. The algorithm can minimize the effect that channel noise gives to the receiving signal. And the algorithm can reduce the MSE and BER. It makes the system work better.
