频谱资源日益匮乏，而无线通信则正迅速发展，如何高效地利用有限的频谱资源从而可靠地支持更多数量的无线应用是一个十分值得研究的课题。如果使用高阶调制的办法，可以在同样的信道上提高传输速率以提高信道利用率，然而当发射功率相同时，高阶调制的性能显然要劣于低阶调制。当然提高通信的可靠性的措施还有分集技术、信道编码等。分集技术使得接收机能够接收到多个独立的发射信号。信道编码则能够提高无线链路通信的可靠性。MIMO技术作为另外一种方法，它具有数据速率高、系统容量大、传输质量高等优点，越来越引起人们的兴趣，尤其在功率、带宽受限的无线信道情形下显现出它的优势。当发射天线之间互不相关时，MIMO系统能够很好地提高系统的抗衰落和抗噪声性能，从而获得巨大的容量。
