New Bounds on Wide-Gap Frequency-Hopping Sequences

IEEE Communications Letters, 2019
In a frequency-hopping (FH) system, to avoid that the received signal would be prone to be interfered, the equipped FH sequence of each user should have wide FH gap, i.e., the adjacent two frequencies should have some gap. In this letter, we extend the Lempel–Greenberger bound and Peng-Fan bounds for wide-gap frequency-hopping sequences (WGFHSs).

Code sequences for frequency-hopping multiple-access systems

IEEE Transactions on Communications, 1995
Summary: A new code construction is given for slow frequency-hopping multiple-access channels. The construction is based on the cyclic concatenation of special subcodes of two Reed-Solomon codes.

Randomness of frequency hopping sequences generated by Hermitian codes

Proceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 2002
Frequency hopping sequences generated by either Reed Solomon (RS) or Hermitian codes (AG) are compared. The results show that AG codes do better than RS codes if the ratio of the number of hits by length of sequences is considered.
