| 摘 要： | 针对矿井隧道内特殊的空间,文章假设了完全不同于地面上散射体的几何分布,提出了一个全新的MIMO信道三维GBSB模型,推导出了该模型的空时相关函数。通过几何解析法,对相关函数和信道容量进行仿真分析,得出了最佳的天线布置方案。仿真结果表明,在矿井环境下合理地布置天线,可以大幅度地提高无线系统的信道容量。

| Abstract: | According to special space of mine tunnel,the paper supposed geometric distribution of scatters which was totally different from the ones on the ground, put forward a new 3D-GBSB model of MIMO channel,and dudeced the space-time correlation function of the model.It simulated and analyzed the correlation function and channel capacity by geometry analytic method to get the best scheme of antennas layout.The simulation result showed that the channel capacity of the wireless system can be enhanced obviously thro... |
