摘要:
为缓解L频段卫星导航信号日趋拥挤的问题,国际电联(ITU)将5 010~5 030 MHz的C频段分配给导航业务,客观上使L与C频段联合导航成为可能。调制方案是导航信号体制设计中的关键环节,设计一种能满足各波段要求的通用调制方案,可有助于降低多频终端的复杂度,加快多波段联合导航的实用化进程。本文针对北斗(BDS)B3信号的频点分布,设计一种L和C频段的双频组合模型,提出将连续相位调制(continuous phase modulation,CPM)作为上述频段的通用调制方案。仿真结果表明:相比于现有调制方案,CPM具有较高的频谱利用率,在码跟踪精度、抗多径、兼容性方面有一定的优势,可满足C频段严格的兼容性约束条件,使各波段中通用信号设计成为可能,为未来北斗卫星导航信号调制方案的设计提供新思路和可行性论证。
