这是一篇基于循环延迟分集的分组预编码和空时频编码技术方面的典型文章(This is a cyclic delay diversity based on the group pre-coding and space-time-frequency coding technology, a typical article)

ITRI CIM Emulator能够读取SML档案，主要功能是用来测试半导体设备的通讯功能，它支持SECS-I/SECS-II/HSMS-SS通讯协议，支持SML格式，具有强大易用的自动化测试功能，免安装即拷即用。 使用前需要先将RS232连接线接好运行软件，选择检视。在设定SECS-I对话窗口中输入相关的通讯参数。(ITRI CIM Emulator can read SML files. Its main function is to test the communication function of semiconductor devices. ITRI CIM Emulator supports SECS-I/SECS-II/HSMS-SS communication protocol, supports SML format, has powerful and easy-to-use automated testing function, and exempts installation and copy-and-play. Before you use it, you need to connect the RS232 connection line to the running software and select the view. Input the relevant communication parameters in the SECS-I dialog window.)

分别上传了多天线系统中的SISO，SIMO，MISO以及MIMO模型仿真程序，对比了不同模型的容量。还有最优算法与最大范数算法的误码率比较程序。很实用！(Upload four system model,SISO SIMO MISO and MIMO,respectively.And compare their capacity.In addition,a BER program is also uploaded based on optimal algorithm and maximum norms)

说明：  可以根据用户需要设计任意的模拟滤波器。只需填入截止频率、通频带等参数，该软件就可自动生成滤波器的电路图，以及各个元件的参数。(this software is very useful for designing filter ,you need only input the data ,then it can generate the circuit.)

说明：  多输入多输出(Multiple-Input Multiple-Output)技术是无线移动通信领域智能天线技术的重大突破。该技术能在不增加带宽的情况下成倍地提高通信系统的容量和频谱利用率，是新一代移动通信系统必须采用的关键技术。(Multiple input multiple output (MIMO) technology is a major breakthrough of smart antenna technology in the field of wireless mobile communication. This technology can double the capacity and spectrum efficiency of the communication system without increasing the bandwidth. It is a key technology that must be adopted in the new generation of mobile communication system.)
