MatlabCodesforMethodOfCharacteristics

基于matlab的单相整流电路，对于初学电力电子技术者极其有用，倾情奉献。(Matlab-based single-phase rectifier, power electronics for the beginner who is extremely useful Decent.)

余弦小波变换源程序，开发环境为matlab(cosin wavelet transform code using matlab)

利用matlab求解网络覆盖问题，代码可以直接运行(Network coverage using matlab to solve the problem, the code can be run directly)

说明：  MATLAB 7编程 数字信号处理源代码(MATLAB)

能够将扫描得到的指纹图像连接并去噪,以便能够更好地与指纹库中的图片进行匹配(the program can improve the connectivity of some fingerprint pictures.)

Radio map builder and particle filter for WiFi indoor localisation using the fingerprinting method

菲涅尔区聚焦多波束天线空间谱估计性能分析(Fresnel zone focusing spectrum estimation performance of multi-beam antenna spatial analysis)

This is a program to study the dynamic instability of cylindrical shell due to parametric excitation.

衰落信道参数包括多径扩展和多普勒扩展。时不变的多径扩展相当于一个延时抽头滤波器，而多普勒扩展要注意多普勒功率谱密度，通常使用Jakes功率谱、高斯、均匀功率谱。( The fading channel parameters include multipath spreading and Doppler spreading. The time-invariant multipath extension is equivalent to a delay-tap filter, while the Doppler spread should pay attention to Doppler power spectral density, usually using Jakes power spectrum, Gaussian, and uniform power spectrum.)

坐标变换，实现3/2和2/2变换。异步电动机矢量控制中使用的(Coordinate transformation, to achieve 3/2 and 2/2 transformation. Vector control induction motor used)
