In the paper, the channel estimation and tracking method for mobile orthogonal frequency division multiplexing (OFDM) systems is developed. The channel estimation method is based on a frequency domain finite impulse response (FIR) filter, while the tracking method is based on a Kalman filter. The proposed method could effectively track the time-variant of the channel with Doppler delay spread. Moreover, the method achieves good performance with low complexity, which makes the hardware implementation facilitated.
