摘要

为了能够更好地利用频率资源，全球导航卫星系统的多种信号使用了二进制偏移载波（Binary Offset Carrier，BOC）调制.传统基于匹配滤波的BOC信号捕获算法为了防止相关峰中的零点降低检测概率，需要采用较小的码相位搜索间隔，这会大幅提升相关处理的计算复杂度.针对该问题，本文提出了基于多相分解的BOC信号高效捕获算法.该算法对捕获中的相关累加进行多相分解，通过基带数据重采样和选择特定码相位搜索间隔，实现了不同搜索相位下相关值的高效复用.对于北斗系统所采用的BOC（1，1）和BOC（14，2）调制，为了达到相同的检测性能，本文所提算法的计算复杂度仅约为传统算法的1/4和1/2，这对卫星导航终端的小型化和低功耗设计具有重要意义.

Abstract

In order to make better use of frequency resources

binary offset carrier (BOC) modulation is used for various signals of the global navigation satellite system. Small code phase search interval is needed for traditional BOC signal acquisition algorithm based on matched filtering to avoid lower detection probability because of the zero points in the correlation peak

which will greatly increase the computational complexity of correlation processing. To solve this problem

an efficient BOC signal acquisition method based on polyphase decomposition is proposed in this paper. The correlation process is polyphase decomposed

and correlation value of different code phase could be reused by re-sampling the baseband data and selecting a specific search interval. For the BOC(1

1) and BOC(14

2) modulation used in BDS

the computational complexity of the proposed algorithm is only about 1/4 and 1/2 of that of the traditional algorithm to achieve the same detection performance

which is of great significance for the miniaturization and low-power design of satellite navigation terminals.
