一本关于非线性时间序列分析的书籍，本来论坛有人上传过，但不能下载了。(One on nonlinear time series analysis of books，Originally it was uploaded, but can not download)

文件用于数字通信信号的调制方式识别，包含调制信号的产生，模拟通信信道，以及特征量的计算（共5个特征量，分两个程序计算），最后是信号调制方式的识别。(Files for digital modulation recognition of communication signals, including modulation signal generation, Simulation communication channel, and the calculation of features(a total of five features, calculated in two programs), and finally the signal modulation recognition.)

以循环的方式随机选择簇头节点，将整个网络的能量负载均匀分配到网络中的每个传感器节点，从而达到降低网络能耗，提高网络生存周期的目的。(Cyclic manner randomly selected cluster head node, the energy of the entire network load evenly distributed to each sensor node in the network, which can reduce energy consumption and improve the life cycle of the destination network.)

依据simulimk中提供的程序设计的跟踪微分算法(Simulimk provided in accordance with the procedures designed to track the differential algorithm)

独立主成分分析与主成分分析代码，速度比较快，而且比较好用(In these first experiments, both ICA and whitened PCA are used to compress the data, and all the components are used for classifying the examples. The classifier used is a 1-NN with Euclidean distance. The results shown in next sections are clear: when a rotational invariant classifier is used (as 1-NN with L2-norm) the classification results of FastICA/whitened PCA are equivalent, while the difference between Infomax and whitened data es significant but small)

前项平滑技术，是空间普技术中解相干的一种重要方法(former smoothing technology, space technology Pronk decorrelation an important method)

EKF的效果需要有test来测验。test中给定了初值来验证EKF的滤波效果(EKF the test results need to test. Test were given to verify the initial value of the filtering effect of the EKF)

在Matlab中运用边缘提取的方法，对图像中的特征图形进行边缘提取(By using the methods of edge extraction in Matlab, the edge feature extraction of graphic image of the)
