ultra wide band simulation 2

This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a three-dimensional Cartesian space lattice comprised of uniform cubic grid cells. Each unit cell within the Yee lattice contains electric fieldcomponents sampled along the edges of the cube and magnetic field

此程序以美国黄石国家公园为例，构造尽可能贴近实际的仿真环境，从而通过仿真得到野火发生频率与野火规模之间的数学模型。这是一个经典的幂率模型，稍作改造好即可模拟“28原则”、“网站点击率”等幂率相关问题。(This procedure to Yellowstone National Park as an example, the actual construction simulation environment as close as possible to the simulated wildfire through the frequency and size of wildfires between the mathematical model. This is a classic power law model, slightly modified to better simulate " 28 principles" , " web site click-through rate" and other power-law related issues.)

近似熵m文件 保证正确运行 绝不骗人(ApEn m file to ensure correct operation will not lie)

说明：  这是基于matlab的单用户注水算法的源程序，(This is a matlab-based algorithm for single-user water source,)

说明：  求解一般线性无约束最优化问题的qp算法程序(Solving the general linear unconstrained optimization algorithm QP procedures)

此文件包含跳频信号的生成和脉冲干扰信号的生成，可以结合二者产生跳频脉冲信号(This file contains the frequency hopping signal generation and pulse interference signal generation, you can combine the two to produce a frequency-hopping pulse signal)

经典的信息论准则估计信号源个数。 使用空间谱估计理论，模拟发射信号由天线阵列接受采样。经过AIC和MDL两种算法，估计出采样序列中信号的个数，所加噪声是白噪声。(Classical information theory for sources number estimation. It s spatial spectrum estimation theory. it analogs transmission signal from the antenna array . It uses two algorithms“ AIC and MDL ”to estimate the number of sampled signal sequence. the added noise is white noise.)

GPS和INS组合导航程序，基于混沌的模拟退火算法，进行逐步线性回归。( GPS and INS navigation program, Chaos-based simulated annealing algorithm, Stepwise linear regression.)
