A Construction of Optimal Sets of FH Sequences

摘要

Frequency hopping spread spectrum and direct sequence spread spectrum are two main spread coding technologies. Frequency hopping sequences are needed in FH-CDMA systems. In this paper, a construction of optimal sets of frequency hopping sequences is presented through perfect nonlinear functions. The construction is based on the set-theoretic characterization of an optimal set of FH sequences. In the procedure, the notion of mixed difference functions is proposed and used.
