摘要 本文提出了在已知最大多普勒频移情况下采用平均法估计信道时 ,信道估计误差与平均区间长度关系的频域分析方法及其完整的解析数学表达式 ,并给出了据此计算出在不同的移动速度情况下的最佳信道估计长度解析公式 ,将其应用于Rake接收机中 ,能大大提高接收机的性能 . A frequency domain error analysis and further a closed form of the error is presented in this paper.The analysis and its results help to adaptively optimize the averaging interval for the channel estimation especially for the 3rd generation mobile communication systems which have to satisfy a wide mobile speed range and as a result the BER performance of the receiver could be improved.
