摘要：

This paper presents a channel estimation scheme for orthogonal frequency division multiplexing (OFDM) in fast varying Rayleigh channels. To estimate the current fading channel, we use not only the known pilot symbols but also the previously estimated channel coefficients. With the previously obtained channel coefficients, we estimate the data symbols and compensate ICI terms. In simulation results, the effectiveness of the proposed method is shown as compared with the polynomial..
