摘要
提出了连续Ｐｉｌｏｔ 信号体制ＣＤＭＡ系统中，高速移动台自适应信道估计的方法，它包括信道变化速率的检测和信道估计积分长度的自适应调整两个部分．仿真结果显示，该信道估计器有效拓展了移动台正常工作的运动速度范围，提高了ＲＡＫＥ接收机的适应性．
A novel CDMA adaptive channel estimator with continuous pilot signal is presented in thes paper, which consists of two parts:a channel changing rate detector and a selector for selecting the most suitable integral length. The simulation results indicate that the adaptive channel estimator work well.
