本文采用计算电磁学的方法对一个典型的室内MIMO-UWB OFDM系统进行了仿真。目标是使用真实的世界环境并考虑真实的天线效果来创建模拟。在每个子载波的基础上检查无线信道的影响。仿真结果表明，信道响应和互信息对子载波有很强的依赖性。此外，我们的分析表明，通过利用信道知识，可以得到一个很大的增加互信息。这导致的结论，自适应调制有可能提供显着增加系统容量。
This paper simulates a typical indoor MIMO-UWB OFDM system using computational electromagnetics. The goal is to create a simulation using a real world environment and taking into account realistic antenna effects. The effects of the wireless channel are examined on a per subcarrier basis. Analysis of the simulation results shows that the channel response and subsequently, mutual information is highly dependent on subcarrier. Furthermore, our analysis shows that by taking advantage of channel knowledge, a great increase in mutual information can be obtained. This leads to the conclusion that adaptive modulation has the potential to offer significant increase in system capacity.
