Channel estimation based on iterative interpolation for wireless communication in OFDM system

OFDM has become the hotspot in the research of wireless communication, and channel estimation is one of the key techniques of OFDM. In this paper, a channel estimation algorithm based on iterative interpolation for wireless communication is proposed. This algorithm first obtains initial estimate of the next receiving symbol, then the precise estimate is acquired by the amendment of the frequency response of the symbols. The simulation results demonstrate that this algorithm can effectively track the channel properties, which leads to its good performance in channel estimation.
