摘要
城市微蜂窝移动通信电波传播环境相当复杂,特别是针对未来陆地蜂窝移动通信系统基于智能天线应用的规范标准要求,建立这种无线传播信道的有效模型无论对理论分析、系统优化设计以及网络工程规划来说都是非常重要的。为此从多径色散信道的特性分析出发,采用电磁散射理论和电波传播原理建立了基于阵列天线的微蜂窝多输入多输出物理信道模型,对刻画信道特性的一些重要性能参数,如空间相关性和时间演化等进行了仿真分析和研究。与有关文献结果的比较,表明了所建立的微蜂窝移动通信信道模型的有效性。
In urban micro-cell communication systems, the radio propagation situation is very complex. Especially for the future land mobile cellular communications where smart antennas will be employed under the standards stated. So it is important to establish an efficient radio propagation channel model for theoretical analyzing, system optimal designing and networks planning. After a review of the multi-path dispersion channel properties, a micro-ceU multi-input multi-output channel model for multi-element antenna systems based on results from Electro-Magnetic （EM） scattering and wave propagation was proposed. Some parameters determine channel performanee such as spatial correlation and time evolution were investigated and simulated. The simulation results match well with measurements available in that of the literature.
