经验模态分解（EMD）方法（平稳化过程）是一种全新的处理非平稳数据序列的方法，其基本思想是：假如一个原始数据序列X(t)的极大值或极小值数目比上跨零点（或下跨零点）的数目多两个（或两个以上），则该数据序列就要进行平稳化处理(Empirical Mode Decomposition (EMD) method (a smooth process) is a new deal with non-stationary data sequence method, the basic idea is: If a raw data sequence X (t) the maximum or minimum number of than the cross-zero (or under the cross-zero) number more than two (or more), then the data is necessary to carry out a smooth sequence of treatment)

OFDM的一些基础步骤，希望对大家的学习有所帮助。(OFDM some basic steps, we want to help learning.)

最小生成树prim算法，Dandn文件给出了输入参数的名称及格式即在调用prim前先输入邻接矩阵D和节点个数n输入prim得到两行的矩阵T,将上下两行数字对应的节点相连即可(Prim algorithm for minimum spanning tree, Dandn document gives the name and format of the input parameters that is called prim before Input adjacency matrix D and the node number n input prim to be two lines of the matrix T, the upper and lower figures correspond to two lines of nodes connected to can)

Arnold置乱变换的matlab代码，函数形式，做数字水印经常用到。(Arnold scrambling transform matlab code, functional form, so often used in digital watermarking.)

说明：  包含卷积码众多资料，并附matlab软件的源码(Convolutional code contains a number of information, with the software source code matlab)

试验 上机 教程 主要对教师 使用(Test on the machine for teachers to use the main course)

实现多普勒信号的处理。 包括信号平滑等操作(Doppler signal processing to achieve. Including the signal smoothing operation, such as)

EEUC的仿真算法，可以与LEACH仿真算法相比较，非常有用(EEUC simulation algorithms can be compared with LEACH algorithm, very useful)

说明：  数据整理，数据和标签和样本数量之间的匹配，当然也可以用其他方法，仅供参考(Data collation, matching between data and label and sample quantity, of course, other methods can be used, for reference only)
