Abstract :
This paper proposes an improved algorithm of PEG, CPEG (Constrained Progressive Edge Growth), for constructing tanner graphs to represent the constraints of PN sequence, which makes the iterative acquisition method applicable for general PN sequences. And simulation results show that the performance of iterative acquisition using CPEG graph is improved by 2.5dB, and the complexity is reduced to the half.
