摘　　要：为实现无线通信网灵活的多级误码率传输保证,从跳频通信的物理层技术出发,提出了一类随机性较好且具有两级互碰撞特性的新型跳频序列集。基于传统汉明最优跳频序列和代数变换,给出了一类满足两级互碰撞特性的跳频序列集的构造算法,通过实例和仿真分析了该跳频序列集的频点碰撞特性。与传统跳频序列集相比,该类跳频序列可提供两级灵活的互碰撞值,为实现跳频多址接入系统两级误码率传输保证提供了基础。该序列具有明显的性能优势,在未来民用和战术跳频通信中具有广阔的应用前景。To meet the flexible multi-level error-rates transmission requirements, a novel frequency-hopping ( FH) sequence set with good random property and two-level cross-hit rates property is introduced from the view of physical layer in FH system. Based on the traditional FH sequence and algebra transform, a con-struction algorithm of the FH sequence set with two-level cross-hit property is presented,then the frequency-hit properties are illustrated by simulation and example. Compared with the traditional FH sequence, the proposed sequence set can provide two-level cross-hit rates, which is the basis to implement two-level error-rates transmission requirement for FH-CDMA system. The sequence has obvious performance advantage and will be found wide application in future civil and tactical FH communication systems.
