说明： 2. 关于无线信道的多普勒谱，请回答以下问题：
(1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请描述产生混叠的各种原因；
(2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理；
(3) 请用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请描述：自己用计算机产生的经典谱是正确的依据。(2. Regarding the doppler spectrum of the wireless channel, please answer the following questions:
(1) in some wireless channels, doppler frequency shift will cause aliasing of the output signals of the wireless channel.Describe the various causes of aliasing;
(2) there is a classic spectrum in the doppler spectrum in the wireless channel, please explain the mechanism of producing this spectrum shape;
(3) please use Simulink tool to write code (s-function mode) to generate a single-path Rayleigh channel, whose doppler spectrum is the classical spectrum, in which the moving rate is 120km/h.And please describe: your own computer generated classical spectrum is the correct basis.)

ITRI CIM Emulator
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.)
