文章分析了MIMO技术的特点,构建了MIMO系统总体框图,分析了MIMO的系统容量在有无信道状态信息下的信道容量。使用MATLAB对MIMO系统进行建模仿真,通过对其在有无信道状态信息情况下,分别进行了MIMO系统平均容量、在10%中断容量下的信道容量仿真分析。仿真结果表明:MIMO系统在低信噪比时有信道状态信息的容量更大,并且随着天线数目的增加而扩大。

A class of aeronautical wide-band channel models is proposed, featuring parking and taxi environments, takeoff and landing situations, and en-route scenarios for ground–air and air–air links. Typical and worst case parameter sets are suggested, based on published measurement results and empirical data. The models are suitable for channel emulators that can be easily implemented on digital computers or in hardware and thus are useful for the validation of digital aeronautical links. A time-domain and frequency-domain implementation of such a channel emulator are derived, and results for a typical multicarrier system are presented. It is shown that the scenarios have distinguishable performance results depending on the underlying maximum ranges and shapes of the Doppler and delay spectra and the presence of a line-of-sight path. Finally, the degrading effects of intersymbol interference and intersubcarrier interference on the multicarrier signal are explained.
