自适应外差滤波器matlab代码：采用调制技术，控制正余弦信号对准干扰的频率，将输入的干扰搬移到的低频进行滤波，滤波处理后的信号再经过一次调制搬移到原来的频率位置，这样我们就得到了合适的干扰复制信号，再将输入信号和干扰复制信号进行差分运算达到抑制干扰的目的(Adaptive heterodyne filter matlab code)

用matlab实现仿射变换，可以做为初学者参考代码学习，很简单(Affine transformation)

基于稀疏表示的正交最小二乘法，使用的语言是matlab，应用比较广阔，设计信号处理中的信号回归，图像处理的压缩等。(Sparse representation based on orthogonal least squares method, the language used is matlab, relatively broad application, design signal processing signal return, image processing, compression and so on.)

This code contains a modeling of a clamping bridge for the stabilizing of the inverter s Inputs Voltage

Database management systems

此代码用于故障诊断特征提取，所提取特征包括传统时、频域特征和时频特征三部分，数据为轴承数据(This code is used when troubleshooting feature extraction, the extracted features, including traditional, frequency domain and time-frequency characteristics of three parts, the data is bearing data)

国家软件标准定义,开发软件的一个流程都在这里了(National software standard definition, software development process are all here in one of the)

说明：  自编函数实现AR模型的最小二乘估计（AR阶数=4）(AR model of self-function of least squares estimation (AR order = 4))

实现弱信号条件下的检测，可以检测到较低信噪比条件下的信号。(weak signal decetion)
