| 摘要: |
| 针对三种常见的信号畸变，给出完善的畸变误差评估指标，从而能够全面评估畸变误差。同时采用提出的评估指标对北斗全球系统B1频段上的基线信号BOC(14,2)及MBOC(6,1,1/11)信号进行评估。所提出的畸变误差评估指标能够用于评估现代卫星导航信号的畸变误差，对现代导航信号体制设计及完好性监测均具有指导意义。 |

| Abstract: |
| The analytical evaluation indexes for three signal distortion errors of BOC(Binary Offset Carrier) signals were developed. Then the proposed evaluation indexes were used to evaluate the distortion errors of BOC(14,2) and MBOC(6,1,1/11) signals, which were the advised basis signals of BeiDou global satellite navigation system. The proposed distortion error evaluation indexes can be used to evaluate the distortion errors of modern global navigation satellite system signals, and it has directive significance to modern signal design and integrity monitoring. |
