摘　　要：通过对实际CDMA前向信道的分析，得出符合广义RAKE（G—RAKE）接收机的发射信号形式。证明了当多径相对时延非单位扩频码片时G-RAKE接收机多余分支的放置位置。对Madab中simulink产生的CDMA前向信道信号进行仿真，结果显示了G—RAKE接收机良好的性能。Based on the analysis of forward CDMA channel, the transmitted signal pattern which in accordance with G--RAKE receiver is obtained. Then the place where the additional finger will be placed is demonstrated. Simulation on the signal of forward CDMA channel generated by Simulink of Matlab shows the good performance of G-RAKE receiver.
