This file is implementing a bluetooth system which is equipped with frequency hopping method, this method is used for system protection against jamming, This is a matlab simulink file.

bp神经网络的应用，这个程序简单实用，大家可以通过调试参数体会一下(bp neural network applications, this procedure is simple and practical, we can taste through the debug parameters)

维纳噪声抑制，1、 实验原理是利用信号之间的相关性进行信号估计，从而将噪声滤除； 2、 辅助观测信号的噪声抑制可利用Wiener-Hopf方程 求出维纳滤波器的系数 ，式中 是 的自相关阵， 是输入信号 和滤波器输入 之间的互相关矢量； (Wiener noise suppression, 1, experiment is the use of the correlation between the signals for signal estimation, which will filter out the noise 2, the auxiliary noise suppression observed signal Wiener-Hopf equation can be obtained by Wiener filter coefficients, where is the autocorrelation matrix, is the input signal and filters the cross-correlation between the input vector )

数学建模中画散点图，伪彩色图，等高线图，三维曲面图；数据可以从excel中直接导入.(Mathematical modeling of scatter diagram, pseudo color map, contour map, 3-D surface chart data from the excel directly.)

计算水平地震作用的一个算例，适合初学者,希望对大家有所帮做。(it s so useful for fressman. )

扩展卡尔曼滤波，适用于弱非线性高斯滤波.较为简单(Extended Kalman filter, suitable for weakly nonlinear Gaussian filter)

包括 MUSIC算法，ESPRIT算法 ROOT-MUSIC算法，ML法能够很好的估计信号的信噪比,ofdm系统仿真 含16qam调制 fft 加窗 加cp等模块。( Including the MUSIC algorithm, ESPRIT algorithm ROOT-MUSIC algorithm, ML estimation method can be a good signal to noise ratio, ofdm system simulation including 16qam modulation fft windowing modules plus cp.)

说明：  分别采用欧拉法、改进欧拉法和隐式梯形法解一阶非线性微分方程dx/dt=ax。(The Euler method, the improved Euler method and the implicit trapezoidal method are used to solve the first-order nonlinear differential equation dx/dt=ax respectively.)

寻找最短路径的程序,希望对大家有用,谢谢!主要是为了完成注册(Finds all pair shortest path.)

matlab从入门到高级进阶的必备好书，看了以后，希望对大家学习matlab有很高的提高！(matlab from entry to senior advanced essential books, looking after, in the hope that everyone has a very high learning matlab improve!)
