Abstract

Due to large search space and multiple peaks of autocorrelation function, fast acquisition of BOC- modulated GNSS signal is a time and resource consuming task. In this paper, a novel hardware architecture for BOC-modulated signal acquisition is proposed. The proposed architecture adopts sub carrier phase cancellation method to remove multiple peaks. By rearranging the correlation order and adopting time division technology, the proposed architecture reduces the hardware cost. Compared with the traditional structures, experimental results show that the number of adders is reduced by 75%.
