MATLAB编写的利用u律函数实现的抑制OFDM峰均比的程序，程序通过运行，通过u率函数对信号压扩后，PAR明显降低(U law written by MATLAB functions for OFDM PAPR suppression program, the program by running through the u signal compression and expansion rate after the function, PAR was significantly lower)

说明：  matlab中的几种滤波器文件，包括对其的仿真(matlab filter in several documents, including the simulation of its)

多种格式求解偏微分方程，有迎风格式，lax-wendorff格式等(A variety of formats to the solution of partial differential equations)

用matlab实现维特比算法译码，程序简单易懂，自己编写的。(Using matlab Viterbi decoding algorithm, the program is simple and easy to understand, I have written.)

直流微网继电保护策略实现S-function的M文件，主保护为母线直流差动保护，基于小波分解的高频故障电流保护，后备保护为过电流保护，针对系统为2进2出的微网，只需将电流值输入，其中第一个输入变量为开关，为保护算法控制开始/关闭。(The relay protection strategy of DC microgrid realizes the M file of S-function. The main protection is busbar DC differential protection. The high frequency fault current protection based on wavelet decomposition and the backup protection is overcurrent protection. For the microgrid with 2 in and 2 out of the system, only the current value is input. The first input variable is switch, which starts/closes for the control of the protection algorithm.)
