Abstract :
For CL code in the L2C signal, the acquisition approach is based on the orthogonality of long PRN code. Hyper code method and the average correlation have certain limits in the overlap and average degree separately. And then, considering acquisition time, reliability and implementation complexity, the improved method that combine the Hyper code method and average correlation method is presented in this paper. The simulation results of performance about the proposed method indicate the feasibility.
