在这里，5.2 GHz的宽带室内多输入多输出（MIMO）信道测量的结果，根据欧盟IST SATURN项目的报告。我们的研究表明，对于非视距（NLOS）的情况下，平均功率延迟曲线拟合指数衰减曲线相当好，因此，在我们的模型中使用了一个简单的宽带模型，单输入单输出（SISO）在COST 259中提出的。此外，研究表明，MIMO信道冲激响应各归一化抽头的协方差矩阵可以很好地近似为发送端和接收端的协方差矩阵的Kronecker积。在此基础上，提出了一种宽带统计模型。蒙特-卡罗模拟表明，测量数据和我们的模型之间相当好的协议。最后，我们使用这个模型来显示一些容量特性的Hiper-LAN/2信道在NLOS室内场景。
Herein, results of 5.2 GHz wideband indoor multiple input multiple output (MIMO) channel measurements under the EU IST SATURN project are reported. Our investigation shows that for non-line-of-sight (NLOS) cases, the average power delay profiles fit the exponentially decaying curve quite well, therefore a simple wideband model for single-input single-output (SISO) proposed in COST259 has been used in our model. Furthermore, the investigations show that the MIMO channel covariance matrix of each normalized tap of the impulse response could be well approximated by the Kronecker product of the covariance matrices seen from the transmitter and receiver respectively. Based on the above results, a wideband statistical model is presented. Monte-Carlo simulations show reasonably good agreement between the measured data and our model. Finally, we use this model to show some capacity characteristics of Hiper-LAN/2 channels in NLOS indoor scenarios.
