摘要
随着扩频通信和CDMA在军用和民用领域的广泛应用,人们对伪随机码的选择提出了越来越苛刻的要求。如何能快速找到产生伪随机码的本原多项式,科研工作者一直在寻找。针对这种情况,笔者结合在科研探索中的实际,提出了寻找本原多项式的窗口法。从伪随机码产生的原理出发,通过分析伪随机码的产生过程,并结合实际,借助MATLAB语言将窗口法实现。最后,利用此窗口法寻找到了部分本原多项式。
With the wide application of Spread Spectrum Communication and CDMA in military and public domain, people's requirements on selecting Pseudo Noise Code are more and more stringent. Researchers are looking for a method to quickly find primitive polynomial that can generate Pseudo Noise Code. In this situation, we put forward a window method combining with the practices in researches. In this paper, the theory of Pseudo Noise Code is introduced, the generation process of Pseudo Noise Code is analyzed, and the window method is realized in virtue of Matlab language. At last, we find part of the primitive polynomial by using window method.
