| 摘 要： | 以一种基于码跟踪多径误差包络的多径抑制性能评估准则为基础,首先根据Double-delta技术的基本原理,首次推导出了其在无限带宽时的码跟踪多径误差公式,并由此得出了Double-delta技术的理论性能计算公式;然后以数值计算的方法分析了不同信道带宽条件下Double-delta技术的多径抑制性能。仿真结果表明,当信... |

| Abstract: | Double-delta technique is one of the most widely-used and actively-investigated multipath mitigation techniques in GNSS.It is significantly important to analyze the multipath mitigation performance of Double-delta technique in band-limited receiver channels,but seldom has it been referred in any former researches.The multipath error formula for Double-delta technique is derived for the first time after the introduction of tits basic theory.Three criteria,envelope peak,effective envelope length and envelope ... |
