In order to minimize or reduce the mutual interference, low-hit-zone (LHZ) frequency-hopping sequence (FHS) sets with optimal periodic partial Hamming correlation (PPHC) properties have been well applied in quasi-synchronous (QS) frequency-hopping multiple-access (FHMA) communication systems. Besides, to better meet the needs of different frequency-hopping communication scenarios, the research on LHZ-FHS sets with new flexible parameters has great significance. In this paper, via Cartesian product, two designs of LHZ-FHS sets are proposed. Meanwhile, we mainly concern the maximum PPHC of newly constructed LHZ-FHS sets. Then, through proper base FHS sets, four classes of LHZ-FHS sets with optimal PPHC properties and new parameters not included in the related literature are introduced.

为了最小化或减少相互干扰，具有最佳周期性部分汉明相关（PPHC）特性的低命中区（LHZ）跳频序列（FHS）集已很好地应用于准同步（QS）跳频多址 (FHMA) 通信系统。此外，为了更好地满足不同跳频通信场景的需求，研究具有新的灵活参数的LHZ-FHS集具有重要意义。在本文中，通过笛卡尔积，提出了 LHZ-FHS 集的两种设计。同时，我们主要关注新建 LHZ-FHS 机组的最大 PPHC。然后，通过适当的基础 FHS 集，引入了四类具有最佳 PPHC 特性和相关文献中未包含的新参数的 LHZ-FHS 集。
