MATLAB工具箱 内容挺丰富，自己查阅有自己需要的自行下载(MATLAB Toolbox quite rich content, their own needs have access to the download)

matlab程序，计算时间差，爱好matlab编程的可以下载(matlab program to calculate the time difference, love can download matlab programming)

改进根升余弦成型滤波，信噪比可达-70dB，性能较标准升余弦提高较大，在TVB2脉冲成型中仿真验证过(Improved root raised cosine shaping filter, SNR up to-70dB, performance than the standard raised cosine larger increase in pulse shaping TVB2 verified in simulation)

用fdkmod函数画出采用4-FSK调制的0:3的调制信号波形，以及调制信号的频谱图(4-FSK modulation with fdkmod function draw 0:3 modulated signal waveform, and a modulation signal spectrum FIG.)

里面包含主元分析PCA的Matlab代码，包括提取主元，求方差贡献率，绘制贡献率直方图等(Which contains the principal component analysis PCA of the Matlab code, including the extraction of the main element, seeking variance contribution rate, contribution rate of histogram mapping, etc.)

自己开发的基于阶跃响应曲线的面积法程序，实验结果良好。(Their own development based on the step response curve area method procedures, the experimental results well.)

说明：  运用粒子群算法进行优化问题分析，程序中以Giewank函数为测试对象，效果不错。(using PSO to conduct optimization, the effect is good based on Giewank function.)

power_SLmodeling.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_SLmodeling.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)
