摘要
利用有限域上二次型理论讨论了p(p为奇素数)元Kasami序列一种扩展形式的相关特性,求出了扩展Kasami序列的相关函数值,证明在一定条件下,扩展Kasami序列最大自相关旁瓣值和最大互相关模值可以接近Welch下限.
In this paper the correlation properties of a family of generalization of p ary Kasami sequences are discussed. The crosscorrelation function values of the generalized Kasami sequences are determined. It is proved that the maximum nontrivial autocorrelation value and the maximum crosscorrelation value of the generalized Kasami sequences can approach to the Welch bound under some conditions.
