image watermarking method

基于MATLAB对FIR数字低通滤波器进行设计，其中的MATLAB源程序通过实验验证(FIR digital low-pass filter design based on MATLAB, MATLAB source verified by experiments)

可用来计算复杂网络的易损性，进而分析网络特性(used to calculate the vulnerability of networks)

基于matlab的语音信号提取与处理程序(Based on matlab voice signal extraction and processing procedures)

说明：  实现gps单点定位，采用matlab实现了GPS单点定位，包括读Ｎ文件、O文件，定位解算，坐标转换等。-(Matlab achieved using GPS single point positioning, including the reading of N documents, O file, locate solver, coordinate conversion.)

Simulates MPSK Modulator/Demodulator. Simulink Platform - Matlab 7.0

提取原始信号的功率谱就可以看出在哪个频带的能量比较高，噪声主要集中在哪里，这样就可以专门分析那个频带的噪声(The power extracted the spectrum of the original signal can be seen in which frequency band energy is high, the noise is mainly concentrated in where, so that it can be devoted to the analysis of the frequency band of noise)

误码率与信噪比对比图形的仿真源码，即BER VS SNR，通信源程序。(BER and SNR contrast graphics simulation code that BER VS SNR, communication source.)

模拟退火工具箱和相关的源代码，非常有用，希望大家共享学习(Simulated annealing toolbox and related source code )

匹配小波的算法仿真。对原始信号进行匹配小波分解后再进行重构，从图中可以看出消噪性能优越。(It s a simulation of match wavelet algorithm. The primitive signal is decomposed by match wavelet and then reconstructed.It is can be seen from the figure that the method has a good denoise performance.)
