| 摘 要： | 研究了在直接序列码分多址(DS-CDMA)系统中,多径环境下一种基于RAKE结构的辅助矢量接收机。该接收机在收集多径信号的同时抑制系统中的多址干扰,从收集的多径信号中估计出信道响应矢量,并利用估计出的信道响应矢量对多径信号进行合并,最后进行判决。仿真结果表明,辅助矢量接收机能够有效地去除DS-CDMA系统中的多址干扰,同时具备良好的抗多径衰落性能,误码性能明显优于RAKE接收机。

| Abstract: | The auxiliary vector receiver for DS-CDMA systems in multipath channels is studied on this paper. This receiver can collect multipath signal. At the same time, it can restrain the multi-access inference （MAI）, and then estimate the response vector of the channels from the collection signal. Next the multi-path signal can be incorporated using the response vector of the channels. At last the decision is made. Simulation results indicate that the receiver not only can eliminate the MAI in the DS-CDMA system, but also provides good anti- multipath fading performance. |
