Low-Hit-Zone Frequency-Hopping Sequence Sets with New Parameters

open access: yesCryptography and Communications, 2012
In quasi-synchronous frequency-hopping multiple-access systems, low-hit-zone frequency-hopping sequence (LHZ-FHS) sets are commonly employed to minimize multiple-access interferences. In this paper, we present (near-)optimal LHZ-FHS sets with new parameters.

New Bound on Partial Hamming Correlation of Low-Hit-Zone Frequency Hopping Sequences and Optimal Constructions

IEEE Communications Letters, 2018
In this letter, a new bound on partial Hamming correlation (PHC) of low-hit-zone frequency hopping (FH) sequences is derived. Then, a new bound on the PHC of conventional FH sequences is also deduced. Furthermore, two new constructions of low-hit-zone FH sequence sets are presented, which are strictly optimal with respect to the bound by Zhou et al ...
