Novel tracking loop of BOC signal based on subcarrier tracking

  • 摘要: 针对二进制偏移载波(BOC,Binary Offset Carrier)调制信号跟踪的模糊性问题,提出了一种新的基于副载波跟踪的环路结构.通过增加副载波跟踪模块,对副载波和扩频码进行分离跟踪,解决了BOC信号跟踪的模糊性问题;针对副载波信号周期性的特点,以正弦波作为本地信号,利用锁相环实现对副载波的稳定跟踪.通过软件仿真,分析对比了该环路的码跟踪误差、跟踪门限和平均失锁时间 (MTLL,Mean Time to Lose Lock)等性能指标.结果表明,新的环路结构能在保证跟踪精度的前提下,提高对弱信号的跟踪性能,具有较高的环路稳定性.
