Construction of Optimal Frequency Hopping Sequence Set with Low-Hit-Zone [PDF]

open access: yesEntropy, 2023
In quasi-synchronous frequency-hopping multiple access (QS-FHMA) systems, low-hit-zone (LHZ) frequency-hopping sequence (FHS) sets have been well-applied to reduce mutual interference (MI).

Low-Hit-Zone Wide Gap Frequency Hopping Sequence Sets With Optimal Average Hamming Correlation

open access: yesIEEE Access, 2021
In frequency hopping (FH) sequence design, the wide gap is an important performance indicator. In this paper, the average Hamming correlation of wide gap FH sequence (WG-FH sequence) sets with low hit zone, which has not yet been reported previously, is ...

A New Differential Frequency Hopping Scheme based on Chaotic Encryption Algorithm

open access: yesGuangtongxin yanjiu, 2022
Aiming at the problem that the two-dimensional uniformity of the frequency hopping pattern in differential frequency hopping communication is poor, and the frequency hopping frequency is easy to be eavesdropped, this paper designs an encryption scheme ...

On the Sidel'nikov Sequences as Frequency-Hopping Sequences

open access: yesIEEE Transactions on Information Theory, 2009
A (v,l, lambda)-FHS denotes a frequency-hopping sequence of length v over a frequency set of size l with maximum out-of-phase Hamming autocorrelation lambda. Recently, Ding and Yin constructed two FHS families for a prime power q satisfying q=ef+1 with positive integers e and f . Theorems 4 and 5 in their paper claim that these two FHS families include
