Frequency Hopping Sequence Sets With Good Aperiodic Hamming Correlation Properties and Large Family Size

In this letter, two constructions of frequency hopping (FH) sequence sets with respect to aperiodic Hamming correlation (AHC) are presented. They have optimal or near optimal family size according to the upper bound on the family size of FH sequence sets with respect to AHC which was derived by Liu et al. Meanwhile, the parameters of the two classes of FH sequence sets are new. The FH sequence sets obtained have large family size and are applicable to the large-capacity systems.
