Frequency hopping sequences with optimal partial autocorrelation property
International Symposium onInformation Theory, 2004. ISIT 2004. Proceedings., 2004We characterize pk-ary (p prime, k integer) generalized m-sequences and generalized GMW sequences of period p2k-1 over a residue class ring R=GF(p)[xi]/(xik) with the "strictly" optimal partial Hamming autocorrelation function (HAF)

Optimal Frequency-Hopping Sequence Sets Based on Cyclotomy
International Journal of Foundations of Computer Science, 2016In this paper, a kind of generalized cyclotomy with respect to the square of a prime is presented and the properties of the corresponding generalized cyclotomic numbers are investigated. Based on the generalized cyclotomy, a class of frequency-hopping sequence (FHS) set is constructed. By means of some basic properties of the generalized cyclotomy, we

Improved Singleton Bound on Frequency Hopping Sequences
2014In this paper, a new bound on the frequency hopping (FH) sequences with respect to the size of the frequency slot set, the sequence length, the family size, and the maximum periodic Hamming correlation is established. The new bound is tighter than the Singleton bounds on the FH sequences derived by Ding et al. (2009) and Yang et al.

On frequency-hop multiple access sequence
1st International Conference on Universal Personal Communications - ICUPC '92 Proceedings, 2003The design of frequency-hop spread spectrum multiple access sequences is discussed. In particular, it is pointed out that the minimum number of pairwise hits between sequences does not necessarily guarantee good sequences in terms of mutual interference between multiple users.

A generalized hyperbolic frequency hopping sequences
Proceedings of 2004 International Symposium on Intelligent Signal Processing and Communication Systems, 2004. ISPACS 2004., 2005We present the problem of constructing frequency hopping (FH) sequences. The new family of FH sequences we have constructed is called generalized hyperbolic FH sequences. The previous hyperbolic FH sequences, derived by S.V. Maric and E.I. Titlebaum (see IEEE Trans. Commun., vol.40, no.9, p.1442-7, 1992), and extended hyperbolic hopping, derived by M.S.

New Constructions for Optimal Sets of Frequency-Hopping Sequences
IEEE Transactions on Information Theory, 2011In this paper, two generic constructions of optimal frequency-hopping sequence (FHS) sets employing d-form functions with difference-balanced property are presented. They generalize the previous constructions of optimal FHS sets using m-sequences and produce new optimal FHS sets that cannot be produced by the earlier constructions.

A Class of Optimal Frequency Hopping Sequences with New Parameters
IEEE Transactions on Information Theory, 2012In this paper, we propose an interleaving construction of new sets of frequency hopping sequences from the known ones. By choosing suitable known optimal frequency hopping sequences and sets of frequency hopping sequences and then recursively applying the proposed construction, optimal frequency hopping sequences and sets of frequency hopping sequences

Sets of Frequency Hopping Sequences: Bounds and Optimal Constructions
IEEE Transactions on Information Theory, 2009Frequency hopping spread spectrum and direct sequence spread spectrum are two main spread coding technologies in communication systems. Frequency hopping sequences are needed in frequency hopping code-division multiple-access (FH-CDMA) systems. In this paper, four algebraic and a combinatorial constructions of optimal sets of frequency hopping ...

Theoretical bound on no hit zone of frequency hopping sequences
Proceedings of the Fifth International Workshop on Signal Design and Its Applications in Communications, 2011Frequency-hopping (FH) sequences with no hit zone (NHZ) can be employed in quasi-synchronous FH code-division multiple-access (CDMA) systems to eliminate multiple-access interference. In this paper, a new theoretical bound on NHZ of FH sequences is derived. Numerical results show that the new bound is tighter than the existing bounds.
