| 摘 要： | 研究一种新型的求帧同步码组自相关函数的简便方法,并在此基础上以帧同步码中的巴克码序列为例,完成了对其穷举算法的编程,快速验证了24位以内的巴克码序列只有目前已搜索到的10组。该方法是以线性代数的基本理论为基础,借助LabVIEW平台强大的矩阵运算功能来实现的。鉴于自相关函数的计算方法与穷举算法实现的难易程度直接相关,该算法使得利用穷举法搜寻各类帧同步码组时计算更加简单、快捷。

| Abstract: | A new easy method for computing autocorrelation function is studied.Based on this,an exhaustive attack method for Barker code is programmed,and as an example,the number of Barker code within the length 24 is ten.The method is based on Linear Algebra and the advantage of LabVIEW in matrix.For that the computing of autocorrelation function is directly related with the implementation of exhaustive attack algorithm,the exhaustive attack method thus become easier and quicker in searching the every other frame sy... |
