| 摘 要： | 本文提出了一种新的采用空时分组码的CDMA系统上行链路的结构。发射端每个用户对发送信号先进行扩频,再对扩频后的信号进行空时分组编码后送至发射天线。同时本文还相应提出了接收端对接收信号的处理方法。仿真结果表明,该结合空时分组码的CDMA系统的误码率优于一般CDMA系统的误码率。

| Abstract: | A novel system structure of the uplink CDMA system combined with space-time block coding is considered. The transmitting signal is spread at the transmitting terminal, and is sent to the transmitting antennas after space-time block coder. Correspondingly a solution to the receiving signal in the receiver is presented. The numerical results show that the performance of the CDMA system combined with space-time block codes is better than that of the conventional CDMA system. |
