摘要/Abstract

摘要： 卫星导航系统中新一代信号的不断提出与发展，满足了高精度及高性能的要求，然而，也出现了频率共享而引起的多信号相互干扰等问题，而裂谱信号的出现在减小与同频信号相互干扰的基础上，可以更好地提高自身的抗干扰能力。为此，在研究裂谱信号产生机理的基础上，针对BOCsin及BOCcos两种调制信号特性，基于接收系统的测试平台，进行了裂谱信号抗干扰性能的分析与比较。

关键词: 裂谱, 二进制偏移载波, BOCsin, BOCcos, 抗干扰

Abstract: The need of high accuracy and high capability is meeted，based on offer and development of new navigation signal，but the cross jamming problem of same frequency signals is offered，so the appearance of split frequency spectrum signal not only minishes the cross jamming with same frequency signals，but also the ability of anti-jamming is improved.So based on the research of split frequency spectrum signal，the anti-jiamming characteristic of BOCsin and BOCcos signals is analysed and compared.

Key words: split frequency spectrum, Binary Offset Carrier（BOC）, BOCsin, BOCcos, anti-jamming
