In quasi-synchronous frequency-hopping multiple-access systems, low-hit-zone frequency-hopping sequence (LHZ-FHS) sets are commonly employed to minimize multiple-access interferences. In this paper, we present (near-)optimal LHZ-FHS sets with new parameters. We first analyze the Hamming correlation of frequency-hopping sequences (FHSs) constructed by the Cartesian product. We then present a new optimal LHZ-FHS set with respect to the Peng-Fan-Lee bound, which is obtained from the Cartesian product of two one-coincidence FHS sets. We also construct a near-optimal LHZ-FHS set from Kumar’s FHS set.
