摘要
为了获得应用于测控通信系统具有优良相关特性的混沌扩频序列集合,提出了截短混沌扩频序列的优选算法。基于中值比较进行平衡序列构造,相对传统方法能够得到更大的筛选序列集合。给出了截短扩频混沌序列的具体优选步骤,并对截短混沌序列和Gold序列在多址系统中的性能展开了比较和分析。
From the point of collecting spread spectrum sequence set applied in TT&C system with good correlation performance, optimized selection of truncating chaotic spread spectrum sequence is proposed in which a greater set is obtained by introducing median value threshold in balance construction compared with traditional method. Detailed optimized selection steps are given, as well as comparison and analysis of utility performance in multiple access system between truncating chaotic spread spectrum sequence and Gold sequence.
