写一个MATLAB程序，实现4个时间同步的CDMA用户的仿真，其中每个用户都使用长度为L=31的不同的Gold序列。每个用户都采用它们代表的Gold序列的二进制（+-1）调制。每个用户的接收端将这个复合的CDMA接收信号相关，而这个复合的信号都在它们各自的序列上受到AWGN的污损（基于按码片相加）。在N=10000信息比特下，仿真估值并画出作为SNR的函数的CDMA通信系统的差错概率。(Write a MATLAB program, the realization of the four time synchronization of the simulation of CDMA users, including the length of each user for use of the L = 31 different Gold sequences. They are used for each user on behalf of the Gold sequence of binary (+-1) modulation. Each user' s receiver will receive the composite CDMA signal, and this composite signal in the sequence of their respective defaced by the AWGN (additive based on the chip by). Information in the N = 10000 bits, the simulation value and draw as a function of SNR of the CDMA communication system the probability of error.)

说明：  一个用于求圆周率pi的matlab算法。题目背景：取一长面积为1平方米的正方形白纸，在白纸的内部画一个直径为1米的圆，如下图所示。此圆恰好与正方形的四条边分别切于一点，它的面积是 pi*（1/2）^2 =pi/4 ,然后，你可以抓一大把芝麻，一粒一粒地随便地扔到白纸上。在你扔麦子的过程中可以请一位朋友帮助记录：一共扔了几次？有几次是扔在圆里面？ 实验结束后，你只须用“芝麻落在圆里的次数”除以“一共扔的次数”得到的结果就是圆的面积。则pi就是“圆的面积*4”了 当然，你扔的次数越多，结果就越精确！()
