testBPSKVB

基于EMD的Hilbert-huang变换(Hilbert-huang transform based on EMD)

说明：  matlab下看地震切片的程序，配合seislab使用(matlab seismic sections look at the procedure, coupled with the use of seislab)

在Matlab对FDTD进行仿真，并对一维，二维及三维电磁传播环境分别编写了程序(On the FDTD simulation in Matlab, and the one-dimensional, two-dimensional and three-dimensional electromagnetic propagation environment programs were prepared)

BP神经网络：是一种按误差逆传播算法训练的多层前馈网络，是目前应用最广泛的神经网络模型之一。BP网络能学习和存贮大量的输入-输出模式映射关系，而无需事前揭示描述这种映射关系的数学方程。它的学习规则是使用最速下降法，通过反向传播来不断调整网络的权值和阈值，使网络的误差平方和最小。BP神经网络模型拓扑结构包括输入层（input）、隐层(hide layer)和输出层(output layer)。(BP neural network: a Press the front back propagation algorithm to train multilayer feedforward network is one of the most widely used neural network model. BP network can learn and store large amounts of input- output mode mappings without prior reveal mathematical equations that describe this map. It' s learning rule is to use the steepest descent method, through a reverse spread to constantly adjust the network weights and thresholds, so that the minimum squared error of the network. BP neural network topology, including the input layer (input), hidden layer (hide layer) and output layer (output layer).)

信号的时移 y(t) = x(t - t0) 其中，t0为位移量。若t0为正数，则y(t)等于将x(t)右移t0秒之后的结果(This program is used to implement the time-shift operation )

matlab labs that will be very good for the beginners at least. Also, we can use this to promote our skills with matlab use.

the matlab code for block truncation code

说明：  使用ga解决tsp问题，使用attp48城市数据(Use GA to solve TSP problems and attP48 city data)

说明：  模拟退火算法来源于固体退火原理，是一种基于概率的算法，将固体加温至充分高，再让其徐徐冷却，加温时，固体内部粒子随温升变为无序状，内能增大，而徐徐冷却时粒子渐趋有序，在每个温度都达到平衡态，最后在常温时达到基态，内能减为最小。(Simulated annealing algorithm is derived from the principle of solid annealing is a kind of algorithm based on probability, high solid heating to fully, then let it slowly cooling, heating, inside the solid particles with the temperature rise to disorder, internal energy increase, and slowly cooling particles become more orderly, and in each temperature to reach the equilibrium state, finally reach the ground state in normal temperature, can reduce to a minimum.)

IMM算法仿真,Matlab源码,用了最小二乘法，EKF，UFK等几种方法比较(IMM algorithm simulation, Matlab source code, using the least squares method, EKF, UFK Comparison of several methods such as)
