Research on Rapid Search Strategy of Long Code
Fang Liu · Jisuanji gongcheng · 2009
In a direct sequence spread spectrum communication system with long period pseudorandom code, the search speed of the pseudorandom code impacts the overall performance of the receiving system seriously. Aiming at the question on rapid search for long code, a rapid search strategy of long code is proposed, which expands the search scope of pseudorandom code adopting expansion and average technologies. Theoretical analysis and numerical results show that the acquisition method can effectively improve the acquisition speed of the pseudorandom code when searching large-scale codes.
