摘要:给出了Galois环上不完全指数和的上界,并在此基础上对Zp2导出的p元Kerdock序列的非周期自相关性进行了研究,给出了序列非周期自相关性的上界,其中p为任意奇素数。结果表明,该类序列具有极低的非周期自相关性,在密码学和通信领域具有潜在的应用价值。最后,还对序列元素的部分周期分布进行了估计。
An upper bound for the incomplete exponential sums over Galois rings was derived. Based on the incomplete exponential sums, the nontrivial upper bound for the aperiodic autocorrelation of the Kerdoek-code p-ary sequences de- rived from Zp2 was given, where p is an odd prime. The result shows that these sequences have low aperiodic autoeorre- lation and provide strong potential applications in communication systems and cryptography. The estimate of the partial period distributions of these sequences was also derived.
