QPSK信号的产生 很好很不错的码源 节省时间 (QPSK signals have a very good source of very good saves time code)

能够进行信号的Hilbert-Huang变换的matlab语言代码，使用的是以前的老算法计算的，但是已经证明可用，希望能对初学者有帮助(Used to implement the input signal of the Hilbert-Huang transform. First proposed calculation method, after validation, can be used.Based on Matlab.)

IIR低通滤波器的matalab实现程序。(IIR low-pass filter matalab implementation process.)

This is my simulation of PMSM. Hope you can edit and use it to your exercise. It is not actually correct but I think it will be useful for you.

说明：  Kmeans实现聚类分析，还有一个用模拟退火优化的Kmeans。(Kmeans implements clustering analysis.)

说明：  通过matlab对均匀光栅，切指光栅，取样光栅等各类光栅的反射特性进行仿真。(Matlab is used to simulate the reflection characteristics of all kinds of gratings, such as uniform grating, cut finger grating and sampling grating.)

ofdma下行自适应资源分配算法仿真方面的几种算法对比。有图。直接点main文件即可运行(ofdma downstream aspects of adaptive resource allocation algorithm for simulation comparison of several algorithms. A map. Main file can be run directly point)

关于短路计算的一些源程序同时是有关matlab优化的源程序(Short-circuit calculations on some of the matlab source code is also optimized source)

高阶谱工具包，用于计算信号的各阶谱结构，得到信号在高阶谱情况下的重要特征(higher-order spectral toolkit)
