摘要
MIMO技术突破了无线频率资源限制,大幅度地提高了无线通信系统效率,故被认为是无线通信技术未来发展的方向。信息论又预示了无线MIMO系统具有潜在的巨大的信道容量。因此,对MIMO信道容量的研究就显得尤为重要。主要是基于上海室外热点地区实测信道数据,利用MATLAB仿真,分析了各种MIMO天线配置对应的信道容量的性能。
MIMO technology breaks through the constraints of wireless frequency resource and greatly improves the efficiency of wireless communication system, so it is considered to be the future direction of the development of wireless communication technology. Also information theory indicates that the wireless MIMO system has the potential huge channel capacity. Therefore, it is particularly important to research on MIMO channel capacity. Based on the results of the measurement channel data in Shanghai outdoor hot spots, this paper mainly uses MATLAB simulation and then analyzes the performance of channel capacity in the case of the various MIMO antenna configurations.
