说明：  用MATLAB实现同步压缩变换SST，好用(Realize synchronous compression transformation, easy to use)

此程序用于OFDM与FBMC的对比，详细描述了UFMC系统的发送和接收的仿真实现过程，并对比相同系统参数下的OFDM系统，发现FBMC系统的优势。(This program is used for OFDM and FBMC contrast, describing the detail of UFMC transmitter and receiver simulation process, and comparing the the OFDM system under the same system parameters to verify the advantages of FBMC system.)

说明：  GPS串口通信程序，新建了一个数据库ACCESS，在显示当前GPS信息的同时可以存储以前记录过的信息，保存在数据库中，便于以后查阅。当前GPS信息包括：时间，经度，纬度，速度，真实航向以及磁偏移(GPS serial port communication program, a database of new ACCESS, show the current GPS information can be stored at the same time the information previously recorded, stored in a database for easy access later. The current GPS information including: time, longitude, latitude, speed, true course and magnetic offset)

调用动态链接库的API实现小灵通手机的PSID读取，有工程文件和生成的文件，还在测试用的DLL(Call the API of the dynamic link library to implement the PSID reading PSID of the PHS , with engineering files and generated files, and also in the test DLL)

。研究了瑞利衰落信道下两跳放大前传协作中继系统的最优化功率分配问题。推导了高信噪比条件下的协作中继系统的中断概率的理论公式. 协作中继 放大前传 最优化功率分配 误符号率 中断概率(Optimal power allocation for two hops amplify- and- forward cooperative relaying communication systems in Rayleigh fading channel was studied. cooperative relaying amplify-and-forward optimal power allocation symbol error rate outage probability)

In this paper the various technologies available so far for wireless transmission of electricity and the need for a Wireless System of Energy Transmission is being discussed to find its possibility in actual practices, their advantages, disadvantages and economical consideration.

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。并请回答：证明自己用计算机产生的经典谱是正确的可能方法。 (On the wireless channel of the Doppler spectrum, please answer the following questions: (1) In some radio channels, the Doppler frequency shift will cause the output signal of the wireless channel aliasing. Please describe the aliasing produced a variety of reasons (2) wireless channel in the Doppler spectrum has a classical spectrum (classic spectrum), please explain the mechanism of produce such spectral shape (3), please use the Simulink tool to write code ( S-Function mode), resulting in a single-path Rayleigh channel, the Doppler spectrum for the classical spectrum, including mobile rate of 120km/h. And requested the answer: that they used computer-generated classical spectrum is the right possible way.)
