Weak signal acquisition based on circular correlation and half-bit
Yi Zhang, Chao-chao Jing, Peng Wu · 2010
In the paper, it analyses circular correlation and accumulation algorithm and further proposes a new algorithm that combines circular correlation with half bit and presents the detailed acquisition steps. The feasibility and effectiveness of the algorithm are verified by the simulation under MATLAB. The results show that the new algorithm can improve acquisition efficiency and sensitivity.
