基于时变频率选取的MIMO无线信道仿真模型研究

针对在复杂的无线通信环境中多输入多输出（Multiple Input Multiple Output, MIMO）信道建模非常困难的问题，提出了一种具有空间选择性、频率选择性、时间关联性的MIMO信道模型，将载波频率、最大多普勒频移、到达角（Angle of Arrival, AOA）分布、角度功率谱以及相邻天线间距等技术整合到一起，研究了不同角度频率谱（Power Azimuth Spectrum, PAS）分布的空间关联系数表示。仿真结果表明，这个关联信道容量与理论信道容量一致，从而验证了该模型的合理性，同时，该模型为MIMO容量、系统容量分析及性能评估仿真提供了有力的工具。

Research of Simulation Models for MIMO Wireless Channels Based on Time-Verifying Frequency Selection

For the issue that it is difficult to modeling of Multiple Input Multiple Output (MIMO) channel in complex wireless communication environment, a MIMO channel model which has spatial selectivity, frequency selectivity, and time correlation is proposed in this paper. Carrier wave frequency, the maximum Doppler frequency shift, AOA (Angle of Arrival) distribution, power azimuth spectrum and adjacent antenna spacing are taken into account integrating. Expressions of the spatial correlation coefficient for different power azimuth spectrum (PAS) distributions were studied. Simulation shows this related channel capacity is consistent with theoretical channel capacity. Thereby the rationality of this modeling was validated. This model provides powerful implement for simulation of MIMO capability, analysis of system capacity and evaluation of performance.
