摘要: 针对互操作信号在性能与处理复杂度上平衡点不唯一的特点,提出了一种非匹配接收模式下的信号性能评估方法,在此基础上为北斗二期B1频点互操作信号提出了4种参考调制方案,并从综合接收性能的角度给出了一种优选方案。与国际上现有的互操作信号调制方案相比,本文提出的优选方案可获得最小的解调损失以及最佳的跟踪性能,在处理方式灵活性方面具有其独特的优势,可以作为我国自主GNSS信号体制设计和优化的一种可行的参考方案。

Abstract: We present a kind of signal performance evaluation method for generic mismatch processing mode.On this basis,four reference modulations for compass B1 band interoperable signal are proposed,and within which,an optimal reference modulation is given based on the comprehensive performance.Compared with existing interoperable signals,the proposal modulation has independent intellectual property right.And it has superiorities in demodulation and tracking,as well as in the flexibility.The experimental results can be regarded as a feasible reference for the design and optimization of the compass signals.
