用七元线形天线阵（ULA） 已知：信号中心波长为2,天线阵元的间距为1米,快拍数为2000，空中有四个 源信号,假设它们的频率：0.015, 0.05, 0.02, 0.035 四个源信号的方向分别为：pi/4 pi/3 pi/6 3pi/4 求： 1）在不加入噪声的情况下,画出传统波束形成法、Bartlett波束 形成法、Capon波束形成法的空间谱图； 2）在加入高斯白噪声的情况下,假设信噪比为10dB，画出传统波束 形成法、Bartlett波束形成法、Capon波束形成法的空间谱图。(7-element linear antenna array (ULA) Known: the signal center wavelength is 2, the antenna element spacing of 1 m, the number of snapshots for 2000, the air there are four Source signal, assuming that their frequency: 0.015, 0.05, 0.02, 0.035 The direction of the four source signals: pi/4 pi/3 pi/6 3pi/4 Requirements: 1) not to join the noise, to draw the traditional beam-forming method, Bartlett, beam Formation method, Capon beamforming method of the space spectrum 2) by adding Gaussian white noise, assuming that the SNR is 10dB, to draw the traditional beam Formation method, Bartlett, beamforming, Capon beamforming method of the space spectrum.)

采用DelayTime_MutualInformation互信息法计算混沌时间序列的delaytime的Matlab原程序(used DelayTime_MutualInformation mutual information calculation mixed turbid time series delaytime Matlab original program)

CAD APPS is a set of Computer Aided Design (CAD) and Exploration Applications (APPS) that were developed for undergraduate Mechanical and Aerospace Engineering (MAE) students. The CAP APPS solve problems that are typically found in MAE courses. The CAD APPS have also been found to be useful to high school students, graduate students, and others.

该程序用Matlab给出了一个利用upml边界条件的很好的示例(The program gives an advantage of using Matlab boundary conditions upml good example of)

hurst指数的matlab源代码，简单实用(the hurst Index matlab source code)

ekf滤波、pda关联滤波、卡尔曼滤波、最小二乘参数估计的仿真建模，以及matlab多项式的学习资料(ekf filtering, pda association filtering, Kalman filtering, least squares parameter estimation modeling and simulation, as well as learning materials matlab polynomial)

改进欧氏距离测度算法，可以比较特征向量的距离相似度(Improved algorithm Euclidean distance measure, you can compare the similarity distance of feature vectors)

说明：  仿真高斯白噪声信道下的dsb信号调制解调，并对传输进行评估（误码率）。(DSB modulation and demodulation of simulated Gaussian white noise channel)

ARM编程特别是系统初始化代码的编写中通常需要实现中断的响应、解析跳转和返回等操作，以便支持上层应用程序的开发，而这往往是困扰初学者的一个难题。中断处理的编程实现需要深入了解ARM内核和处理器本身的中断特征，从而设计一种快速简便的中断处理机制。需要说明的是，具体的上层高级语言编写的中断服务函数不在本文的讨论范围之内(ARM programming particular system initialization code in preparation usually need to achieve interruption of response Jump and return analysis, etc, in order to support the upper application development, which is often plagued by a problem beginners. Interruption of programming needs in-depth understanding of the ARM processor core and features of the interruption itself, be able to design a simple and rapid interrupt handling mechanism. There is a need to explain the specific upper prepared by the high-level language service interruption is not the function within the scope of discussion)
