改进papr，对于改进papr的程序给了完整的代码，具有参考价值(Improved papr, for improving the procedures papr)

说明：  用51单片机完美地解决凝露现象。防止元件老化(The dew phenomenon can be perfectly solved by 51 single chip computer. Preventing component ageing)

TD-SCDMA物理层原理，了解物理层技术，了解信道编码的基本原理。(TD-SCDMA Physical Layer Principle)

信号的捕获(直接序列扩频系统的matlab仿真实现，包括M,GOLD序列生成，信道建模，噪声，扩频，解扩)(Signal capture (direct sequence spread spectrum system simulation matlab implementation, including M, GOLD sequence generation, channel modeling, noise, spreading, despreading))

2.4寸彩屏显示渐变颜色彩条，c语言编程实现(2.4 inch color screen display color tapered color strips)

Dynamic Subchannel and Bit Allocation in multiuser mimo-ofdma systems.

模仿超级终端风格的RS232串口调试工具 这是一个模仿Windows系统带的超级终端风格的RS232串口调试工具。非常容易读取和写入端口，发送支持ASCII字符模式，可以打开二进制文件以16进制格式显示发送。支持工作内容保存，下次加载。 里面的那个动画窗体加载出现蛮有意思，大家可以学习下。尤其对调试AT指令之类的比较方便。(RS232 serial debug tool imitating super terminal style This is a SuperTerminal style RS232 serial debugging tool that mimics the Windows system. It is easy to read and write ports, send ASCII character mode and open binary files to display in 16 binary format. Support work content to save, next load. Loading the animated form inside is quite interesting. You can learn from it. In particular, it is more convenient to debug AT instructions.)

基于esprit算法的宽带信号（线性调频信号）doa估计(DOA estimation based on esprit)

这是自由空间路径损耗的代码。里面有多个m文件(This is the code of path loss in free space. There are multiple M files in it.)

说明：  研究d2d通信加中继节点来优化蜂窝小区边缘用户通信，并通过MATLAB仿真(The D2D communication and relay nodes are studied to optimize the edge user communication of cellular cell, and the simulation is carried out by MATLAB.)
