说明：  设计一个有干扰的直接序列扩频通信系统， PN码由m序列产生器产生，经过高斯白噪声信道。在接收端接收到的信号包括“有用信号+高斯白噪声+干扰”，将接收信号进行解扩，判决，得到用户的信号检测结果，绘制不同的扩频增益（增益值为10，30，50）下，误比特率随信噪比Eb/N0的变化曲线。(Design of a direct sequence spread spectrum interference system, PN code generated by the m sequence generator, after white Gaussian noise channel. Receives the signal at the receiver, including &quot useful signal+ Gaussian white noise+ interference&quot , will receive the signal despreading, judgments, get the user' s signal test results, draw a different spreading gain (gain value of 10,30, 50), the BER curves with the signal to noise ratio Eb/N0.)

CDMA系统中的多用户检测技术性能比较，包括MMSE,DC，OMD(CDMA system in multi-user detection performance comparison, including the MMSE, DC, OMD)

计算多速滤波器以及其优化算法和加快速率的提高(this program can help you improve the filter )

程序首先是编写2个输入，1个输出的隶属度函数；接下来的是模糊规则，一共49条；然后用解模糊函数得出控制量U，解模糊用到得规则是取隶属度最大的那个数即MOM算法。(The program first is to write two inputs, one output membership function next is fuzzy rules, a total of 49 then come to control the amount of ambiguity function U, ambiguity was used to take the membership rules are the biggest that number that MOM algorithms.)

说明：  关于SDE数值方法的工具包，主要有欧拉数值方法、milstein数值方法(Tool for SDE numerical methods)

在matlab平台下产生信号序列通过QPSK方式调制通过高斯信道以及瑞利信道，对其中的过程的信号时域以及其频谱，星座图情况进行分析(Matlab platform in the signal sequence under way through the QPSK modulation, as well as through the Gaussian channel Rayleigh Road, on which the process of time-domain signal and its spectrum, constellation diagram analysis)
