A Chaotic Frequency Hopping Sequences by Mid Multi-bit Quantified and its Proper ties

文章结合伪随机数生成技术,提出了一种具有较好独立性与随机性的混沌跳频序列中间多比特量化方案,不仅减少了序列生成的运算量,同时也大大扩展了跳频序列周期。文章还研究了中间多比特量化方案产生跳频序列的均匀性、跳频间隔和汉明相关性等与跳频通信系统性能相关的因素。结果表明该方案生成的跳频序列复杂度高,具有良好的多址性能。

A new method of mid multi-bit quantifying chaotic sequences is propose d which has excellent independent and stochastic characters from the technique o f generating pseudo-random numbers. The method can not only reduce operations of generating sequences, but also increase the period of FH sequences. Furthermore , the factors relating to properties of a FH system of the FH sequences by the p roposed method were researched, such as uniformity property, hopping gap, Hammin g correlation property, and so on. The results show that the FH sequences genera ted by this method has high complexity and suit for the multi-address communicat ion.
