“…In 2016, Wang et al [16] constructed two classes of optimal LHZ FHSs with new parameters based on Cyclotomy, the discrete logarithm function and the Chinese remainder theorem. In 2019, Yin et al [19] obtained two constructions of LHZ FHS based on m-sequence and d-form functions with difference-balanced property.…”

<p style='text-indent:20px;'>Frequency hopping sequences with low hit zone is significant for application in quasi synchronous multiple-access systems. In this paper, we obtained two constructions of optimal frequency hopping sequence sets with low hit zone based on interleaving techniques. The presented low hit zone frequency hopping sequence sets are with new and flexible parameters and large family size which can meet the needs of the practical applications. Moreover, all the sequences in the proposed sets are cyclically inequivalent. Some low hit zone frequency hopping sequence sets constructed in literatures are included in our family. The proposed frequency hopping sequence sets with low hit zone are contributed for quasi-synchronous frequency hopping multiple access system to reduce or eliminate multiple-access interference.</p>

“…Different from conventional FHSs design, in the area near the origin, the MI values of low-hit-zone (LHZ) FHSs remain low among different users. In the past, several designs of LHZ FHS sets [4]- [14] have been obtained and proved to conform to the Peng-Fan-Lee bound [15]. However, when constructing frequency hopping sequence (FHS) sets, it can be found that the optimal sets do not always exist for all lengths and sizes.…”

The low-hit-zone (LHZ) frequency hopping sequence (FHS) sets are widely applicable in quasi-synchronous frequency hopping multiple-access (QS-FHMA) systems. In order to reduce mutual interference (MI) in the zone around the signal origin between different users, we recommend the LHZ FHS set instead of the conventional FHS set. In this letter, we propose a design of LHZ FHS sets via interleaving techniques. The obtained sequences can be confirmed that they are near-optimal in relation to the Peng-Fan-Lee bound.
