基于双平行线阵的声矢量传感器的MUSIC算法 用于在高斯白噪声环境下估计信号的到2维达角度 (MUSIC algorithm based on dual parallel linear array of acoustic vector sensor it can be used to estimate the signal in Gaussian white noise environment to the two Vader angle)

该程序用matlab编写数值积分方法，包括梯形公式，Simpson公式和Romberg算法，在main.m文件测试三类算法。这是数值计算方法是必须掌握的代码。(The program is prepared using matlab numerical integration methods, including trapezoidal formula, Simpson and Romberg algorithm for three kinds of formulas in main.m file for testing. Is the numerical calculation method must master code.)

apply a lowpass filter to a watermarked audio signal to test the robustness input : vector representing the watermarked audio file output : vector representing the watermarked audio file corrupted by a highpass filter

介绍了如何利用 MATLAB 及其图像处理工具箱进行数字图像处理, 并通过一些例子来说明利用 MATLAB 图像处理工 具箱进行图像处理的方法。 (Introduction to digital image processing using MATLAB and its image processing toolbox, and through some examples to illustrate the use of MATLAB image processing Toolbox for image processing method.)

说明：  THIS CODE IS INTENDEED TO GET THE PLOT FOR THE SIMULATION RESULTS OF THE DFIG

由于多径和移动台运动等影响因素，使得移动信道对传输信号在时间、频率和角度上造成了色散，如时间色散、频率色散、角度色散等等，因此多径信道的特性对通信质量有着至关重要的影响，而多径信道的包络统计特性成为我们研究的焦点。根据不同无线环境，接收信号包络一般服从几种典型分布，如瑞利分布、莱斯分布和Nakagami-m分布。(Because multipath and mobile and other sports influence factor, makes mobile channel in transmission in time and frequency signal and Angle caused the dispersion, such as time dispersion, frequency dispersion, Angle dispersion, and so on, thus multipath channel of communication with the characteristics of quality is very important, while the effect of multipath channel (the statistical properties become the focus of our research. According to different wireless environment, receiving signals envelope general subject to several typical distribution, such as Rayleigh distribution, rice distribution and Nakagami-m distribution. )
