摘要：
This paper proposes a channel frequency response estimation method for OFDM systems based on Kalman filter. Method uses only pilots from current OFDM symbol and consists of two stages. At first stage performs pilot's filtration in forward and backward directions and combining the results in each point. At second stage performs extrapolation the channel frequency response between pilots in forward and backward directions and combining the results.
