Abstract

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). In this paper, we propose three constructions of LHZ FHS sets with new parameters via interleaving techniques. The obtained sequences can be verified that they are optimal with respect to the Peng-Fan-Lee bound.

Keywords: frequency hopping sequence set; frequency-hopping multiple-access; interleaving techniques; low-hit-zone; maximum periodic Hamming correlation.
