设p是奇素数,e为奇数,n=2e,且d=(pe+1)2/2(pk+1),其中k|e.研究周期为pn-1的p元m序列{st}与其采样序列{sdt+l}(0≤l≤gcd(d,pn-1)-1)之间的相关性,确定了相关函数Cd(τ)的所有可能取值.
Let p be an odd prime, e be an odd integer, n=2e and d=(pe+1)2/2(pk+1), where k|e. Theauthor studies the cross-correlation between a p-ary m-sequence { st } of period p^n-1 and itsdecimated sequence {sdt+l} (0≤l≤gcd(d, p^n-1)- 1). The possible values of the cross-correlation function Cd (r) are determined.
