摘要
针对B1C信号捕获的灵活性和多样性,提出将TMBOC信号与BOC(1,1)信号分别对其进行非匹配捕获的研究。首先建立B1C信号数学模型,对算法研究原理进行了数学推导,其次针对信号捕获的检测概率进行了分析,并对非匹配捕获中存在的信噪比损失给出了理论分析,并对实际采集到的B1C信号做捕获仿真研究。仿真表明,BOC(1,1)信号捕获能够获得更高的峰均比,而TMBOC信号在捕获B1C信号导频分量时峰均比更优,但整体相较前者峰均比下降约0.46 dB,算法的研究为B1C信号同步提供了新的思路。
Aiming at the flexibility and diversity of B1 C signal acquisition, the non-matching acquisition of TMBOC signal and BOC(1,1) signal is proposed. Firstly, the mathematical model of B1 C signal is established, and the principle of algorithm research is mathematically deduced. Secondly, the detection probability of signal acquisition is analyzed, and the theoretical analysis of the signal-to-noise ratio loss in non-matching acquisition is given. The B1 C signal is used for acquisition analysis. The simulation shows that the BOC(1,1) signal acquisition can obtain a higher peak-to-average ratio, while the TMBOC signal has a better peak-to-average ratio when capturing the B1 C signal pilot component, but the overall peak-to-average ratio is reduced by about 0.46 dB. The research of the algorithm provides a new idea for B1 C signal synchronization.
