divider

说明：  基于DCT的水印图像matlab代码，主要是水印嵌入和水印提取两大主要部分(DCT-based image watermarking matlab code, mainly watermark embedding and watermark extraction are two main parts)

说明：  信号处理中的加窗程序，可以加汉宁窗等窗函数(Windowed signal processing program, you can Hanning window function windows, etc.)

说明：  OQPSK的Matlab/Simulink调制解调仿真系统，包括匹配滤波，载波恢复，定时恢复等重要模块，可以观察眼图，仿真误码率，帮助理解OQPSK系统(OQPSK Matlab/Simulink simulation system modulation and demodulation, including matching filter, Carrier Recovery, timing recovery and other important module, we can observe the eye, simulation BER help understand OQPSK system)

ROOT-MUSIC的matlab仿真源码，基于求根方式的music算法，避免了谱峰搜索，优化了计算复杂度(ROOT-MUSIC for matlab simulation source code, algorithm-based Roots music the way to avoid the peak search, optimization of the computational complexity)

pre-emphasis filter and modulate audio signal

提供了PID控制的几个MATLAB程序包括：增量式PID控制，PID极点配置控制，以及自校正PID控制。(Provides several MATLAB program of PID control includind: incremental PID control, PID pole placement control, and self-tuning PID control.)

This program will give you image with different types of noise added to it and will show you effect and comparison of all

说明：  gardner位同步技术实现，matlab编程实现(Realization of bit synchronization with MATLAB.)

SVM分类程序，可以进行多类分割，该程序的优点是可以直接运行处结果，对SVM初学者十分有利。(Svm classfication program which could run fluently without boring small bugs.)

该程序是在flac下运行的，没找到flac，所以用matlab表示了，供岩土力学研究方向学习(The program is run under flac, did not find flac, so use matlab shows for rock mechanics research study)
