时间序列分析模型构建方法、过程及步骤,并通过假设的时间序列用MATLAB软件,实现了模型的定阶、模型参数的估计过程。(To get the Lds MOdel. )

说明：  对数字信号进行BFSK调制，然后通过高斯白噪声信号后，检测其误码率！(The program s function is to modulate a signal with BFSK,then let the signal go pass a channel of guassian white nosie.At last,The program detects the BER of the signal.)

This is demo for rbpf_gauss.

Contemporary Communication Systems Using Matlab

根据D.C.CHU提出的计算CAZAC序列的算法，计算出CHU序列的matlab程序。包括自相关函数，FFT变换后的CHU序列，以及CAZAC序列的一些特性，还提供D.C.CHU的算法原文(According to the calculation made by CAZAC sequence DCCHU algorithm to calculate the CHU sequence matlab program. Including the self-correlation function, FFT transformed CHU sequence, as well as some of the characteristics CAZAC sequence)

说明：  可以求一个物体的质心，在获取物体图像后。希望大家多多交流(Can request an object centroid, after access to the object image. Hope that more exchanges)

光子晶体的能带图计算，其实质就是电磁本征值（复矢量场）的问题。利用平面波展开磁场，引入f(r)=1/eps(r)，再利用倒格矢G将f(r)展开，将两者代入光子晶体的支配方程，最后得到一个平面波展开的方法的线性方程组，最终转化为求解其特征值向量的问题。(Energy band diagram of the photonic crystal, its essence is the electromagnetic eigenvalues ​ ​ (complex vector field).The linear plane wave expansion magnetic field, the introduction of f (r) = 1/eps (r), re-use reciprocal lattice vector G will expand f (r), the two substituted into the governing equations of the photonic crystal, and finally get a plane wave expansionequations, and ultimately into solving the problem of its eigenvalues​ ​ .)

分支定界，找出最优解，此编程是以六个特征为例进行编程的。(Branch and bound, to find the optimal solution, this program is based on six characteristics of the program as an example.)
