摘要
BOC调制技术在扩频通信中的应用已日趋广泛。为此,本文在对BOC调制信号的功率谱和自相关特性进行深入研究,以及将其与BPSK调制相比存在的优势进行深入分析的基础上,以BOC(10,5),BPSK(10.23)为例,进行了基于FFT的同步捕获环路的设计与仿真,并重点就不同干信比条件下两者的捕获性能进行了分析。结果表明,在一定条件下BOC调制信号具有更好的抗干扰能力,为进一步抗干扰技术的研究提供了理论基础。
Binary-Offset-Carrier waveforms will be applied widely in the spreading communication, so based on the deeply research on power spectra and autocorrelation characteristic of BOC waveforms and the deeply analysis on the advantage compare to the BPSK waveforms, the FFT in-phase acquisition ring has been designed and simulated, besides, the acquisition ability of this two waveforms on the different J/S is analyzed. The result shows that the BOC waveforms have the better anti-jamming ability in the given condition, and they also provide theoretical foundation for the further research of anti-jamming technical.
