spectrum sensing for cognitive radio using energy detection

这是一个用系统模型辨识用的PSO程序,它主要是用于系统的参数未知时,此时比较方便.(This is a used system model identification procedures used in PSO, it is mainly used for systems with unknown parameters, the more convenient at this time.)

gaussian kernel with matlab

当要隐藏信息时,在MATLAB的命令窗内输入命令: hide = myhide(carry,signal,x,y)； carry 用你的原始载体文件名代替，signal 用你所要隐藏的文件名代替 carry 和 signal 都必须是 *.* 的形式（注意不能省略单引号） x,y 是选取隐藏信息的位置坐标，在（x,y）和（y,x）处 生成的伪装载体文件名为hide.bmp 注意myhide.m文件，载体文件，隐藏文件都要在当前目录(current Directory)下 当要提取信息时，在MATLAB命令窗内输入命令： behidden = myinhide(carry,x,y)； carry 用你的伪装载体文件名代替,格式为 *.* （注意不要丢掉单引号） x,y 是选取隐藏信息的位置坐标，在（x,y）和（y,x）处，这必须和嵌入时所选位置一致。 提取出的信息文件名为behidden.bmp 同样，要注意behidden.m和伪装载体文件都要在当前目录(current Directory)下(when to hide information, in order MATLAB within a window orders : hide = myhide (carry, signal, x, y); Carry with you the original document name instead vector, signal used to hide your name in the paper and instead carry signal must be in the form of*.* ( not to single quotes omitted) x, y is to select the location of hidden information coordinates (x, y) and (y, x) The formation of camouflage vector document, entitled hide.bmp attention myhide.m documents, vector documents hidden all the documents in the current directory (current Directory) to retrieve information when, in order window MATLAB import order : behidden = myinhide (carry, x, y); carry using your camouflage vector file name instead, the format for*.* (take care not to lose a single quote) x, y election Hiding information )

exercise1:为基于小波变化与局部能量的图像融合方法 exercise2:为基于自适应算法的图像融合算法 myfunction1~myfunction5:为性能指标评价函数(exercise1: To change and local energy based on wavelet image fusion method exercise2: adaptive algorithm based image fusion algorithm myfunction1 ~ myfunction5: performance indicators for the evaluation function)

信号的预处理，去除趋势项，以达到我们所要的信号的形式，效果比较好(Signal pre-processing to remove the trend term, we want to achieve in the form of signals, results were better)

《matlab实例》中有关遗传工具箱的算法实例，希望对大家有帮助。(" Matlab example" in the genetic algorithm toolbox instance, we want to help.)

全息图生成与复现，可以实现全息图的生成与复现，可以参考。(Hologram generation and reproduction, can generate a hologram and reproduction, can refer to.)

坐标系转变，通过运行，很好的代码，哈哈哈(Coordinate system transformation, by running, a good code)

输入任意采样数据，进行prony分析，给出指数形势的组合并指定后续数据点，进行数据趋势预测； http://en.wikipedia.org/wiki/Prony s_method(Anylysis the input data using prony method, and also can be used for prediction the trend of the movement. http://en.wikipedia.org/wiki/Prony s_method)
