Low Complezity Channel Estimation and Tracking Method for High Speed Mobile Communication Systems

摘要：

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.
