matlab 程序，WCDMA的程序，用MATLAB实现3G手机(SDR based MATLAB program aboutWCDMA. SDR in WCDMA)

这是关于matlab中常用的算法，希望对大家有帮助(Matlab commonly used algorithms, hope to have everyone help)

This function Skeleton will calculate an accurate skeleton (centerlines) of an object represented by an binary image / volume using the fastmarching distance transform.

MATLAB仿真，主要是三厢10KW的晶闸管整流仿真，可以研究研究。(10 kW Thyristor Controlled Rectifier)

电能质量扰动信号信号通过hilbert变换得到瞬时频率，瞬时幅值，hilbert谱，边际谱等重要特征，从而实现特征提取。(Power quality disturbance signals are obtained by hilbert transform to obtain instantaneous frequency, instantaneous amplitude, hilbert spectrum, marginal spectrum and other important features, in order to achieve feature extraction.)

时频分析工具——径向高斯核时频分布。为了在时频分布平面内不出现交叉项，则在模糊函数域内应有效去除互分量而仅保留自分量。设计一个与信号相匹配的核函数可以达到上述目的。基于信号的径向高斯核时频分布是一种比较理想的时频分布(Optimal radially Gaussian kernel time-frequency representation)
