Construction of Bent Sequences and Gold-like Sequences

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.
