摘要

我们比较了Alamouti时空块编码MC-CDMA系统在室内和室外现实场景下采用零强迫或最小均方误差检测方案的性能。这两种场景考虑了系统的两种不同配置。实验结果表明，空间分集显著提高了MC-CDMA系统的性能。因此，Alamouti的STBC MC-CDMA方案充分利用了频率和空间分集的优势，可以被认为是第四代移动无线电系统空中接口下行链路的一个非常现实和有前途的候选方案。

STBC MC-CDMA systems for indoor and outdoor scenarios

We compare the performance of Alamouti's space-time block coded MC-CDMA systems for indoor and outdoor realistic scenarios with zero forcing or minimum mean square error detection schemes. Two different configurations of the system are considered for the two scenarios. The different results obtained as well for indoor as for outdoor scenarios demonstrate that spatial diversity improves significantly the performance of MC-CDMA systems. Then, Alamouti's STBC MC-CDMA schemes derive full benefit from the frequency and spatial diversities and can be considered as a very realistic and promising candidate for the air interface downlink of the 4th generation mobile radio systems.
