摘要
文中研究了在没有任何先验信息的条件下伪随机码的三阶累积量,推出了具体的表达式.并对结果进行了验证。然后提出了基于三阶累积量的伪随机码特征参数提取算法,通过该算法可以得到表征伪随机码特征的三个参数:周期、码元宽度、本原多项式。最后对算法进行了验证。
In this paper,the third-order cumulant of pseudo-random code is studied without any pre-knowledge and expression is gived.The result is validated.And then characteristic detection algorithm of pseudo-random code based on third-order cumulant is presented.The period,chip duration and primitive polynomial of pseudo-random code can be detected using the algorinthm.Lastly,the algorithm is validated.
