| 摘 要： | 跳频通信具有优良的抗干扰性能和多址组网的能力,在军事通信和民用移动通信中得到了广泛的应用.跳频序列的设计是跳频通信系统的关键技术,对跳频系统的抗干扰性能具有决定性的影响.提出了一种基于RS(L,2)码跳频序列的产生方法,并采用对偶频带法对其进行宽间隔处理.其性能分析和仿真结果表明,这种宽间隔RS码跳频序列的图案分布均匀,相邻跳频点的跳变间隔较大,具有良好相关特性:汉明自相关旁瓣是0,汉明互相关不大于1.

| Abstract: | FH communication has excellent anti-jamming performance and the ability of multi-access network, which is widely used in military and civilian mobile communications. The design of FH sequences is a key technology in FH communication systems, which has a decisive impact on the anti-jamming performance of the system. A method based on RS（L, 2） code is designed to produce FH sequences, and the wide interval treatment is done to these sequences by dual sub-band method. The performance analysis and simulation show that the patterns of these FH sequences are uniformly distributed. The intervals between the adjacent FH points are larger than the given gap. They have good correlation properties： the sidelobes of Hamming auto-correlation are 0, while the values of Hamming cross-correlation are not larger than 1. |
