摘　　要：多输入多输出(MIMO)技术应用于移动通信系统中可以提高频谱利用率,增加通信系统的容量,提高用户传输速率,因此,该技术已经成为后3G的关键技术之一。其信道容量不仅和通信环境有关,而且和阵元间信道响应的相关系数有很大的关系。为了对设计的MIMO系统进行评估,则需对其性能进行测试。提出了根据测试相关系数,间接得出信道传输矩阵H的方法。并在实验室环境下,以多天线系统为例,通过采集试验数据,对相关系数做了分析计算。MIMO bandwidth efficiency technology has been used in mobile communications system to increase the , the channel capacity and the data rate, and it has become one of the key technologies for 3G and beyond systems. The capacity of MIMO systems is dependent on the communications scenarios as well as the correlation of the coupling between antenna array elements. And this correlation is closely related to the antenna topologies. With the PHS system as an example, we make some measurements, and the measured data are used to validate the designing of the MIMO system and evaluate the performance of the MIMO technology. We can also extract propagation parameters and derive the capacity results from the measured and simulated data.
