| 摘 要： | 本文介绍了第三代移动通信标准WCDMA(FDD)中基于时分复用的导引符号辅助瑞利衰落信道下的信道估计.提出了一种新的利用两个连续时隙的导引符号估计出的信道参数进行最小二乘意义下二次曲线内插的信道参数估计方法.仿真表明本方法能有效地估计出时隙中数据段的信道参数,尤其在高速及变速运动情况下,Rake接收机的性能得到了显著的改善.

| Abstract: | Estimation of Rayleigh fading channels using time multiplexed pilot symbols in WCDMA (FDD) is considered.Method of interpolation on a second-order curve using the instantaneous channel estimation of two successive slots based on least square method is presented.It is demonstrated by computer simulations that the channel distortion on data symbols in a slot can be estimated effectively compared to the method using simple linear interpolation,and the performance of the Rake combiner is improved especially in fast moving cases. |
