说明：  该PPT着重阐述了matlab语言的绘图功能，包括二维绘图、三维绘图及各种特殊图形，并对MATLAB中的相关语句进行了说明。(The PPT focuses on the matlab language, drawing functions, including two-dimensional drawing, three-dimensional graphics and a variety of special graphics, and MATLAB, are described in the relevant statement.)

多输入多输出（MIMO）系统是在无线通信智能天线技术的基础上发展起来的，其主要特点就是在通信系统的收发两端采用多天线配置，以解决未来移动通信系统大容量、高速率传输和日益紧张的频谱资源间的矛盾。(Multiple-input-multiple-output (MIMO) is a communication technology that multiple antennas are set at transmitters and/or receivers. The system capacity and frequency spectrum efficiency of communication systems can be improved by this technology without extra frequency bandwidth and with no additional power expenditure . )
