Test and Evaluation of Accuracies of MBOC Signals Using a Digital IF Signal Simulator and a Software Receiver

摘要: 在对MBOC信号的码跟踪噪声和多径误差进行理论分析的基础上,借助于所开发的数字中频信号模拟器和软件接收机进行了闭环测试评估。通过将数字中频闭环测试结果与理论预期值和模拟器仿真值进行对比分析,从多个层次有效验证了MBOC(6,1,1/11)相对于BOC(1,1)和BPSK-R(1)的测距精度改善。

Abstract: This paper focuses on close-loop test of code tracking noise and multipath error en-velope of MBOC signals based on a digital IF signal simulator and a software receiver. The experimental results were analyzed and compared with theoretical expectations,and the accuracy improvements of MBOC(6,1,1/11) versus BOC(1,1) and BPSK-R(1) are validated effectively.
