具有较少自相关值的分圆序列在通信系统和密码学中都有广泛的应用.设p≡1 mod 3为素数,我们计算了GF(3)上一类非平衡的、周期为P的、三阶分圆的序列的自相关值,并进一步给出素数P的条件,使得此序列的自相关值为3值.%Cyclotomic sequences with a few correlation values have wide applications in communication systems and cryptography. Let p ≡ 1 mod 3 . We calculate the autocorrelation values of a class of unbalanced cyclotomic and periodic p sequences of order three overGF(3) . Moreover, we support a condition of prime p such that it has 3-level autocorrelation values.
