A demo for image segmentation using iter

使用MATLAB对十六进制字符串进行转换，转换成分贝数的比特流，用于多媒体音频处理（仅供大家参考）(using matlab to convert hexadecimal string to a stream of bytes in decibel numbers，for multimedia audio processing)

matlab得接收机放入仿真程序，很有参考价值，值得学习一下(matlab get the receiver into the emulation program, useful and worth learning about)

一种快速图像融合新算法，提升图像的光谱信息和空间信息(A Novel Fasr Image Fusion Algorithm)

说明：  本文件是用matlab来实现的D-S证据理论代码。可以进行DS证据理论的推到验证(This document is achieved by matlab code DS evidence theory. DS evidence theory can be pushed to the validation)

根据信息熵建立分配模型，接着用熵值法进行合理分配的程序(Established based on information entropy distribution model, followed by entropy reasonable allocation procedures)

利用Matlab仿真软件，完成如图1所示的一个基本的数字通信系统。信号源产生0、1等概分布的随机信号，映射到16QAM的星座图上，同时一路信号已经被分成了实部和虚部，后边的处理建立在这两路信号的基础上。实部、虚部信号分别经过平方根升余弦滤波器，再加入高斯白噪声，然后通过匹配滤波器（平方根升余弦滤波器）。最后经过采样，判决，得到0、1信号，同原信号进行比较，给出16QAM数字系统的误码。(Using Matlab simulation software, as shown in Figure 1 to complete a basic digital communications systems. Signal source such as arise over the distribution of 0,1 random signal, is mapped to 16QAM constellation diagram, at the same time all the way the signal has been divided into real and imaginary parts, behind the deal with the establishment of these two signals in the basis. Real part, imaginary part of the signal, respectively, after a square root raised cosine filter, then add white Gaussian noise, and then through the matched filter (square root raised cosine filter). Finally, after sampling, the verdict has been 0,1 signal, to compare with the original signal is given 16QAM digital system error.)

输入信号的时域和频谱分析 输入信号为ft=[5cos(600*pi*t)+4cos(90*pi*t)+9]/18 输入信号为高频和低频信号的叠加：高频300Hz，低频45Hz( Of the input signal in time domain and spectral analysis of the input signal is ft = [5cos (600* pi* t)+4 cos (90* pi* t)+9]/18 input signal for the high-frequency and low frequency signal superimposed: frequency 300Hz, 45Hz low frequency)
