MIMO多天线系统可以大幅度提高无线信道的容量和信道的质量,因而研究多天线系统对移动通信有很大的意义。在有限的无线通信资源短缺的情况下,发展多天线技术以及合作分集技术显得尤为重要。文章分析了这两种技术的优势所在,并且提出了几项可能的创新。
MIMO multi-antenna system can greatly improve the capacity of wireless channel and the quality of channel. Therefore, studying multi-antenna system is of great significance to mobile communication. In the absence of limited wireless communication resources, it is particularly important to develop multi-antenna technology and cooperative diversity technology. The article analyzes the advantages of these two technologies and presents several possible innovations.
