中文摘要：

该文研究Bent序列和Gold-like序列，设计了3类怏速生成的Bent序列，此外，基于Klapper（1993）对几何序列相关性的分析，递归地构造了一类Gold-like序列，所得的Gold-1ike序列涵括了Khoo，Gong和Stinson（2002）递归生成的Gold-like序列。根据Olsen，Scholtz和Welch（1982）给出的Bent序列簇的构造方法，该文得到的Bent序列可以迅速地构造Bent序列簇。此外，该文得到的Gold-1ike序列可以用来设计大周划的扩频序列簇。

英文摘要：

In this paper, three families of Bent sequences that can be quickly generated are presented. Then based on the analysis of correlation of geometric sequences by Klapper in 1993, a family of Gold-like sequences is recursively constructed, which contains the Gold-like sequences constructed in 2002 by Khoo, Gong and Stinson. On account of the theory of Olsen, Scholtz and Welch, three Bent sequence families used in a DS CDMA system can be quickly obtained by the Bent sequences here. And sequence families with large periods can be obtained by Gold-like sequences recursively constructed.
