Heston模型参数校准

说明：  变速恒频双馈风力发电机基于电子磁链定向的空载并网仿真模型(Variable speed constant frequency doubly-fed wind generators no-load parallel simulation model )

实现坐标系的逆变换，即将dq坐标转换为abc坐标(dq TO abc)

DWT Watermark a example for new beginner, you can edit this file like yours and develop new code for better future

说明：  广义Tikhonov正则化及其正则参数的先验选取(Generalized Tikhonov Regularization and Prior Selection of Regular Parameters)

捷联惯性导航与GPS组合导航。采用matlab实现。采用自适应算法对其进行处理。并取得了很好的效果。(Strapdown inertial navigation and GPS Navigation. Using matlab to achieve. Adaptive algorithm used to deal with them. And has achieved good results.)

This Matlab code shows how to perform edge detection by Sobel method in horizontal & vertical direction and the effect of increasing and decreasing the threshold value . Besides, you can try to perform the edge detection by other method in the same ways such as Prewitt , Roberts , Canny and others.

说明：  oqpsk信号，滚降系数分别为0.4，0.7，1.0.信噪比为20bB(OQPSK signal, roll-off coefficients were 0.4,0.7,1.0. 20bB SNR)

fft谐波分析的实例，并求出THD即谐波畸变率 (Examples fft harmonic analysis, and find THD)

雷达信号，线性调频型号的脉冲压缩。包含线性调频型号、脉冲压缩、以及匹配滤波器的实现。(Radar signal, LFM pulse compression models. Model includes chirp pulse compression, and the matched filter implementation.)

该算法，是基本的Em算法，可以直接调用，经过试验真的很不错，另外里面还有很多源代码，每个源代码都可以直接调用，算法中含有比较细致的描述。
