利用y(n)=x(n)-y^2(n-1)+y(n-1)， x(n)=au(n),u(n)为阶跃序列，这一算法，计算了0.001-0.999之间数字的平方和，并给出图形，并与matlab自身的函数power进行了比较，给出了差值的图形(Calculates the square sum of the Numbers between 0.001 0.999, and the graphics is given, and with the function of matlab power are compared, and the difference of the graphics is presented)

传统RAKE接收机MATLAB程序，后面我会发改进的(traditional RAKE receiver MATLAB procedure, I will be made to improve the)

说明：  matlab实验 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？ (matlab experiment with a given polynomial, y = x3-6x2+5 x-3, generated a set of data (xi, yi, i = 1,2, ..., n), then add random noise in yi (available rand generation (0,1) uniformly distributed random number, or rands generated N (0,1) random numbers), then xi and yi to add a random disturbance polynomial fitting for the three times, compared with the original coefficient . If 2 or 4 times for polynomial fitting, the result?)

This file designs two stage Nyquist filters with a given rolloff and desired ripples of Dc and Ds. The design aims to find the lowet number of multipliers. The main file is called Design_Double.m The matlab script is based on the design method in the following article: A. Eghbali, T. Saramä ki, and H. Johansson, "On two-stage Nyquist pulse shaping filters," IEEE Trans. Signal Processing, vol. 60, no. 1, pp. 483-488, Jan. 2012. Please cite the above article if you use this file. In case o
