Rational-Dilation Wavelet Transforms (RADWT)

线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标加速度信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)

说明：  基于MATLAB的任意时刻三相短路电流计算(MATLAB-based three-phase short-circuit current calculations at any time)

基于matlab的小波分析程序，可以广泛应用于各行业，主要用于分析小波周期、频率等(Wavelet analysis based on matlab procedures, can be widely used in various industries, mainly for wavelet analysis period, frequency, etc.)

need matlab codes which shows the segmentation of the image in boundries. and showing the limitations of image.

永磁同步电机的直接转矩控制 可以学习S函数的编写 PID可以调节 想要的直接拿去(Direct torque control of permanent magnet synchronous motor can learn the writing of the S function of PID can adjust to take it directly)

无线信道建模，含matlab代码，可以帮助大家学习无线信道的只是，并用matlab巩固概念(Modeling the Wireless Propagation Channel)

根据地震记录的统计特征和相应假设，本文采用 ARMA 模型描述地震子波，基于 高阶累积量的 ARMA 模型地震子波提取方法不仅可在压制高斯色噪声的同时保留所需 地震信号的相位信息(For the cumulant based ARMA (autoregressive moving average ) model seismic wavelet extraction method could not only retain the pahse information of the seismic wavlet while eliminating the colored Gaussian noise, but also provide a parsimonious, more efficient )
