| 摘 要： | MIMO技术优势明显,但实用化方面由于硬件实现的困难而阻力重重.协作通信技术利用单天线终端相互共享天线可以虚拟M1MO结构,这为MIMO的实用化提供了新的思路和途径.基于TD-SCDMA下行协作通信系统(TDS-CC)的设计,构造了虚拟MIMO系统,并对该系统在不同条件下进行了仿真分析,结果说明虚拟MIMO系统在性能方面优于其他MIMO系统,具有良好的应用前景.

| Abstract: | MIMO technology has great potential advantages in many areas, but it has more difficulties in practical application. Cooperative communication (CC) technology can use the antenna sharing of single antenna terminals to construct virtual MIMO, which provides a new thought and method for the practical application of MIMO. Based on the TDS-CC system scheme design, a virtual MIMO system was constructed. Simulation result demonstrates that the performance of this virtual MIMO system surpasses other MIMO system and shows good prospect. |
