bsg.c - block layer implementation of the sg v4 interface.

对不理想环境下信号MUSIC算法在小角度时的分辨能力进行仿真。(The signal is not an ideal environment on the MUSIC algorithm in the resolving power of a small angle to simulate.)

可以实现盲均衡算法MCMA+DD，效果较好(Blind equalization algorithm can achieve MCMA+DD, better)

这是一个普通的、容易理解的卡尔曼跟踪滤波器的程序，对初学者有较大的帮助(This is a common, easy to understand the procedure of the Kalman tracking filter, a great help for beginners)

利用维纳滤波实现噪声中的语音信号恢复，产生chirp信号，噪声为高斯白噪声，噪声叠加在chirp信号上，构成观测信号x(n),使用编程方法实现使用维纳滤波滤除高斯噪声。(Wiener filtering the voice signal recovery in the noise generated chirp signal, the noise is Gaussian white noise, noise superimposed on the chirp signal, constitute the observed signal x (n), using the programming method using the Wiener filter filter Gaussian noise.)

这个程序再matlab2012b版本上调试成功，以前在毕业设计的时候在网上找到的资料，希望对大家有用，数字水印算法实现（matlab程序包），包含有DCT水印嵌入算法，DWT水印嵌入算法，以及水印攻击和性能测试程序。参考价值极大(This program debug version then matlab2012b success in graduate design information previously found on the Internet when we want to be useful, a digital watermarking algorithm (matlab package), including a watermark embedded DCT algorithm, DWT algorithm embedded watermark, watermark attack and performance testing procedures. Great value)

此函数可实现桑原滤波器，降低噪声的同时保留边缘内容图像的二维非线性滤波器。以下代码示例： RGB = imread("saturn.png") ； 我 = rgb2gray(RGB) ； J = imnoise(I,"gaussian",0,0.005) ； Y = kuwahara(J,5,true) ；

Diskstra最短路径算法的c++源程序，以及编译好的matlab动态链接库，学习留形学习算法及程序必备。(Diskstra shortest path algorithm c++ source code, and compiled matlab dynamic link library, learning algorithms and procedures remain an essential form of learning.)
