In this paper, a general framework of constructing the optimal frequency-hopping sequence
(FHS) sets is presented based on the designated direct product. Under this framework, we …

This paper is focused on the optimal design and performance analysis of a novel class of no-
hit-zone frequencyhopping sequences (NHZ-FHSs) in quasi-synchronous FH multiple …

For a quasi-synchronous frequency/time hopping (FH/TH) code-division multiple-access
(CDMA) system which involves many users, the low-hit-zone (LHZ) FH/TH sequence set with …

Frequency hopping (FH) sequences play an important role in FH spread spectrum
communication systems. In this paper, a new theoretical bound on the FH sequences with …

In frequency-hopping spread spectrum systems, frequency-hopping sequences (FHSs) are
widely used to alleviate the interferences caused by the hits of frequencies. In this paper …

In this paper, some general properties of the Zeng-Cai-Tang-Yang cyclotomy are studied. As
its applications, two constructions of frequencyhopping sequences (FHSs) and two …

In frequency-hopping sequence (FHS) design, the average Hamming correlation is an
important performance indicator. In this paper, the average Hamming correlation of low-hit …

In this paper, we construct three classes of strictly optimal frequency-hopping sequence
(FHS) sets with respect to partial Hamming correlation and family size. The first class is …
