CW脉冲信号的仿真，加多普勒延时后的频谱图(CW pulse signal simulation, Jiaduopule spectrum after delay)

说明：   改进的牛顿法求解： 方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*. 设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程 例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式. 方程中的系数a0由你得到的根p*来确定. (improve Newton's method : Construction of the equation : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : Your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.)

MATLAB实现的移位寄存器，可以很容易在网上找到框图，原理也很简单，适合初学者参考。(MATLAB implementation of the shift register, you can easily find online diagram, the principle is very simple, suitable for beginners reference.)

说明：  BP算法的matlab实现，能较好的得到结果，误差范围较小(BP algorithm matlab implementation, can get better results, less error range)

this code is used for signal equalization in receivers
