An Interval Vector Based Research on the Primitive-LFSR Sequences
-
摘要: 距离向量是本原-LFSR序列的重要参数，但目前关于距离向量的研究还很少。该文基于距离向量，首先证明了m=2时采样猜想是正确的，然后对本原-LFSR的采样性质进行了研究，最后给出了Z本原-LFSR序列和本原-LFSR序列新的构造方法。Abstract: Interval vector is a crucial parameter of primitive-LFSR, but the reserch about the interval vector is little. Based on interval vector, the correctness of decimation conjecture is first proved when m=2, and then some properties about the decimation sequence are given. Finally some new methods are given to construct Z- primitive-LFSR and primitive-LFSR sequences.
