利用环分解和分圆类的差集偶构造

Constructions for Difference Set Pairs Based on Ring Decomposition

基于环分解并结合分圆类方法,构造两类参数为(pq,q,pkf,kf,kf)(q=ef+1为素数幂)和(k(k+1)/e,k,+1,e,e)的差集偶,推广了李建周等的研究结果.

Two types of difference set pairs are constructed by means of ring decomposition and cyclotomic classes. The obtained difference set pairs have parameters as follows： （pq, q, pkf, k f, k f）（q= e f＋ 1 is prime power） and （k（k＋1）/e,k,＋1,e,e） The result improves the one made by Li Jian-zhou et al.
