V-BLAST结构的ZF检测算法性能，分别在无干扰消除和有干扰消除的系统性能(ZF detection algorithm performance V-BLAST structure, respectively, and there is no interference to eliminate interference cancellation system performance)

真的是一个好程序，基于人工神经网络的常用数字信号调制，小波包分析提取振动信号中的特征频率。( Really is a good program, The commonly used digital signal modulation based on artificial neural network, Wavelet packet analysis to extract vibration signal characteristic frequency.)

deboor算法，B样条，程序简单易懂，很实用(deboor algorithm, B-spline)

说明：  （拟合） 用给定的多项式，y=x3-6x2+5x-3，产生一组数据(xi,yi，i=1,2,…,n),再在yi上添加随机干扰(可用rand产生(0,1)均匀分布随机数,或用rands产生N(0,1)分布随机数)，然后用xi和添加了随机干扰的yi作的3次多项式拟合，与原系数比较。 如果作2或4次多项式拟合，结果如何？ ((Fitting) with a given polynomial, y = x3-6x2+5 x-3, generated a set of data (xi, yi, i = 1,2, ..., n), then add a random disturbance yi ( can be generated rand (0,1) uniformly distributed random number, or rands generated N (0,1) distribution of random numbers), and then added with xi and yi for random interference of the 3 times polynomial fitting, and the original coefficient. If 2 or 4 times for polynomial fitting, the result?)
