Doppler-spectrum-of-radio-channel
1. 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。请清楚的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S-function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。并请回答：证明自己用计算机产生的经典谱是正确的可能方法。
(Doppler spectrum of radio channel 1, please answer the following questions

仿真技术在光纤通信实验教学中的应用
通过两个例子，将Optisystem和matlab这两个软件结合进行光学仿真，两个例子分别为光波频率右移和光波幅度调制。通过这两个例子，能很好的理解这两个软件的协同仿真。上传的文件包括文献和源码，还有optisystem的osd文件，文件很全。(Two examples are used to combine the two software Optisystem and MATLAB for optical simulation. The two examples are the right shift of the light frequency and the modulation of the amplitude of the light wave. Through these two examples, we can well understand the collaborative simulation of these two software. Upload files, including documents and source code, as well as the optisystem OSD file, the document is very complete)
