信息科学与通信工程中卷积码的MATLAB程序的编写(Information Science and Communication Engineering in the convolutional code written MATLAB program)

微粒群算法的matlab程序，好用，对测试函数进行优化(Particle swarm algorithm matlab program, easy to use,)

此程序是针对文献《基于相关函数的多振动信号数据融合方法》撰写的matlab程序，属于多源信息融合(This program is for literature, " based on the relevant multi-function vibration signal data fusion," wrote the matlab program, part of multi-source information fusion)

基带信号周期采样的分析与仿真设计低通信号，对该信号进行周期采样，最后从采样数据中恢复原始信号；改变采样频率，给出相应的仿真结果；考察前端抗混叠滤波器的作用和必要性；分析后端理想恢复滤波器是否唯一。( Periodic sampling of the baseband signal analysis and simulation to design low pass signal, the signal is periodic sampling, finally recover the original signal from the sampled data changing the sampling frequency, gives the corresponding simulation results examine the front of the role of anti-aliasing filter and necessity analysis backend ideal restoration filter is unique.)

获取一个文件夹的创建时间、文件夹中文件内容及文件创建时间等信息(Get a folder was created, the contents of files in a folder and file creation time, etc.)

实现上行链路的程序怎样进行计算和下行链路的计算 (Procedures to achieve uplink calculated how)

使用Scilab编写的粒子群算法，例子比较简单，无混沌搜索(Scilab prepared using particle swarm optimization, for example, relatively simple, non-chaotic search)

说明：  自适应中值滤波器的滤波方式和传统的中值滤波器一样,都使用一个矩形区域的窗口Sxy,不同的是在滤波过程中,自适应滤波器会根据一定的设定条件改变(即增加)滤窗的大小,同时当判断滤窗中心的像素是噪声时,该值用中值代替,否则不改变其当前像素值,这样用滤波器的输出来替代像素(x,y)处(即目前滤窗中心的坐标)的值。(Adaptive Median Filter for filtering methods and the same as the traditional median filter, use a rectangular area of the window Sxy, different in the filtering process, the adaptive filter in on certain Presumed Conditions change (an increase of ) filter window size, while when the judge is the filter window center pixel noise, the median value is used instead of, or does not change its current pixel value, so that the output with a filter to replace the pixels (x, y) Office (that is, coordinates of the current filter window centered) values.)
