| 摘 要： | 针对传统BOC调制信号捕获方案的捕获性能较低或者计算量较大的问题,提出了一种新的折中捕获算法。该算法分析BOC信号频谱特征,通过将左右边带频谱进行相位翻转处理后再叠加的方式,在保证计算量较小的情况下得到了较理想的捕获性能,是两种传统捕获方案的折中选择。仿真和理论分析表明,本文算法可以适用于各种调制阶数BOC信号的捕获处理,并且减小了计算量,具有较好的捕获性能。

| Abstract: | Focusing on the problem that the traditional acquisition schemes of Binary Offset Carrier (BOC) modulated signals have poor acquisition performance or large amount of calculation, a new compromise algorithm is presented in this paper. Through analysis of spectrum characteristics, reversal and superposition of the upper and lower sideband spectrum of BOC signal, an ideal acquisition performance is obtained with a low computation load. The simulation results show that the proposed algorithm is applicable for acquisition of BOC signals modulated by different modulation factors. |
