摘要
MIMO技术是无线通信领域的重大突破,在不增加系统带宽的情况下,显著地提高系统的数据传输速率和通信质量。该文首先描述了MIMO系统模型,然后对MIMO系统的信道容量进行讨论和仿真分析,最后讨论空时编码技术和对基于Alamouti空时码的系统性能进行仿真分析,从而证明了MIMO系统的优越性。
MIMO technique is a great breakthrough in the field of wireless communication.It can greatly increase the data transmission rate and performance without expanding bandwidth.The model of the MIMO system is described first,then the channel capacity is studied and simulated,finally,the space-time coding is analyzed and the Alamouti space-time coding is simulated to validate the outstanding performance of the MIMO system.
