摘　　要：提出了一种RAKE接收机的算法,它利用时分—同步码分多址(TD＿SCDMA)无线通信系统的基站发出的导引信号获得TD＿SCDMA下行链路的信道参数估计.该算法可减小移动用户的多径干扰.本文的性能分析和计算机仿真证明,在典型多径衰落传播情况下,所给RAKE接收机算法可以获得更好性能.This paper develops a RAKE receiver algorithm that makes use of the pilot signal broadcasted by the TD-SCDMA (division-synchronous code division multiple access) base station to obtain channel parameter estimation in the downlink of TD-SCDMA wireless network. The algorithm can reduce the multipath interference for the mobile units. The performance analysis presented in the paper and the computer simulations confirm that the proposed RAKE receiver algorithm achieves a better performance under typical multipath fading propagation conditions.
