DBSCAN

This is a short code script to describe CDMA coding and decoding mechanisms

本程序为应用小波变换进行信号压缩。由于本程序涉及到了小波变换的函数，因此可能涉及到一些时频分析工具箱的函数。程序中应用db3小波进行3层分解，选用全局阈值进行阈值处理，即对各高频系数使用同一个阈值，进行阈值处理。(This procedure for the application of wavelet transform for signal compression. Since this procedure involves the wavelet transform of the function, it may involve a number of time-frequency analysis function of the toolbox. Procedures for the application of layer 3 to db3 wavelet decomposition, selection of the overall threshold threshold treatment, that is, on the high-frequency coefficients using the same threshold, the threshold for treatment.)

matlab编写的Gabor小波滤波器，包括一维和二维两种情况。非常实用(Gabor wavelet filter matlab prepared, including a two-dimensional and two-dimensional case. Very useful)

说明：  基于模糊PID的温度控制系统,通过matlab平台对基于模糊PID的温度控制系统进行设计(PID temperature controller design based on fuzzy control: fuzzy control and PID control combine to achieve PID adaptive approach to control system temperature by means of fuzzy control. This Fuzzy- PID strategy is not to replace the use of fuzzy control PID control, but the traditional control methods to improve and expand, both to maintain a simple and conventional PID control system structure, easy to use, robust, and high control accuracy advantages, but also the use of fuzzy inference PID parameters to achieve the PK, IK, DK-line self-tuning, both the fuzzy control flexibility, adaptability features, compared to simply have a good control effect either)

求信号的时频熵，对非平稳信号进行emd分解后，求时频熵，得出其故障特征(For the signal s time-frequency entropy, the nonstationary signals are EMD decomposition, and time-frequency entropy, the fault feature)
