Optimal Design of Special Wide Gap Frequency Hopping Sequence Sets with No-hit-zone

The special wide gap (WG) frequency-hopping (FH) sequence set with no-hit-zone (WG NHZ FHS set), combining the characteristics of both the special WGFHS set (which features stricter WG property) and the NHZ FHS set, endows the FH communication system with robust anti-interference capability, enabling superior anti-jamming performance and enhanced security. In this paper, a general method is introduced for designing WG NHZ FHS sets. By selecting different classes of sequence sets as component sequence sets, the new method can generate a new class of special WG NHZ FHS sets, the length of the NHZ for which can take even number greater than 3. The experimental results show that the new FHS sets exhibit favorable performance according to the theoretical bound.
