摘要
针对目前基于RS码生成的非重复跳频序列周期较短、序列复杂度较低、工程实用性不强等缺点,提出一种改进的RS码宽间隔跳频序列生成方法。使用长周期的RS码,采用非线性转移矩阵法将其转换为跳频序列,再用对偶频带法对其进行宽间隔处理。性能仿真结果表明,与以往的方法相比,改进的跳频序列在增加了序列复杂度的情况下,仍具有良好的均匀性、随机性和汉明相关性,且实现较简单,工程实用性较强。
Aiming at the disadvantages of current non-repeating FH sequences based on RS code which have short periods, low complexity and weak engineering practicability, an improved method generating wide interval FH sequences based on RS code is proposed. A long-period RS code is used and transformed to FH sequences by a nonlinear matrix, and the wide interval treatment is done to these sequences by dual sub-band method. The results of simulation show that the improved FH sequences have good equality, randomicity and hamming correlation with higher complexity, which can be realized easily and have strong engineering practicability.
