| 摘 要： | 针对WCDMA上行链路的结构，介绍了一种基于卡尔曼滤波和线性内插的信道跟踪方法。Kalman滤波器通过线性内插所提供的粗略的数据估计值来准确地获得信道参数的LMMSE解，跟踪信道的变化。仿真结果表明该方法能有效跟踪快速衰落信道，改善系统的性能。

| Abstract: | This paper introduces a channel tracking method based on Kalman filter and linear interpolation for the uplink of WCDMA systems. Kalman filter uses the estimated data from linear interpolation to correct the predicted channel coefficients and tracks the channel variation. It is demonstrated by the computer simulation that this method can track the fading channel effectively and the system performance is improved. |
