Implementation of Quadrature Amplitude Modulation-Demodulation

用于接收机的载波同步，利用锁相环实现解调，用于相干解调(Carrier for receiver synchronization, phase-locked loop to achieve demodulation for coherent demodulation)

永磁同步电机的自抗扰控制仿真模型,采用了速度电流环控制。(Simulation model of active disturbance rejection control for permanent magnet synchronous motor)

Zhouzhiqiang的图像融合MATLAB源码，对应其2016年发表的论文Perceptual fusion of infrared and visible images through a hybrid multi-scale decomposition with Gaussian and bilateral filters(Perceptual fusion of infrared and visible images through a hybrid multi-scale decomposition with Gaussian and bilateral filters)

LTE Downlink Physical Channel processing

求解任意阶数（大于0）的分数积分，要求输入时间数组和函数值数组(Solving any order (greater than 0) fractional integral, requiring the input time array and the array of function values)

这是一份高阶统计量的资料，有相关的程序，目前高阶统计量是研究的热门话题，对于地震子波的高精度提取有重要意义。(This is a higher-order statistics of the data full of relevant procedures,and at present higher-order statistics is a hot topic which is very important and significant for high-precision seismic wavelet extraction.)

this m-file describe a power amplifier model.it is useful to model a power amplifier which has am-am and am-pm effects.

说明：  EMD降噪程序，与stanford开发的小波工具箱和小波降噪工具箱联合使用！(EMD noise reduction procedures, and stanford Development Toolbox Wavelet Toolbox and Wavelet combination!)

基于MATLAB的GUI滤波器设计资料。(Based on MATLAB the GUI filter design information.)
