中文摘要：

给出了一个快速算法决定有限域Fq上周期为upn序列的极小多项式.设p,q,u为不同素数,q为模p2的本原根,m为最小正整数使得qm≡1modu和gcd（m,p（p-1））=1.利用一个算法把有限域Fq上周期为upn序列化为几个有限域Fq（ζ）上周期为pn序列,其中ζ为一个u次本原单位根,从而利用肖国正等的算法得到每个周期为pn序列的极小多项式.

英文摘要：

A fast algorithm for determining the minimal polynomial and linear complexity of a upn-periodic sequence over a finite field Fq is given.Let p,q,and u be distinct primes,q a primitive root modulo p2,m the smallest positive integer such that qm≡1 mod u,and gcd（m,p（p-1））=1.An algorithm is used to reduce a periodic upn sequence over Fq to several pn-periodic sequences over Fq（ζ）,where ζ is a u-th primitive root of unity,and an algorithm proposed by Xiao et al.is employed to obtain the minimal polynomial of each pn-periodic sequence.
