摘要
同步是高速DS/FH混合扩频系统的关键技术之一。针对高速DS/FH混合扩频系统的需求,提出了一种快速同步方法,通过在随时间变化的同步信道上传输同步信息,并通过能量检测辅助等待搜索的方式捕获同步信号。数学分析表明,此方法用较少的系统资源,获得了较短的捕获时间和较强的抗干扰性能。
Synchronization is one of the key techniques of high-speed DS/FH hybrid system. A fast synchronization scheme was proposed in consideration of the need of high-speed DS/FH hybrid system, it is achieved by transmitting the synchronization information in time-dependent FH synchronization channels, and capturing the synchronization signal with a waiting strategy assisted by energy detection. The mathematical analysis indicates that, with moderate resource consumption, this scheme can have short capturing time and good anti-jamming performance.
