Abstract
Based on factor graph and sum-product algorithm, an iterative acquisition algorithm for multiple PN codes is proposed. This algorithm combines the BP decoding algorithm and the chip level MUD as an iterative loop to fulfill the task of parallel acquisition for multiple PN codes. Simulation and analysis results show that the performance of this algorithm is slightly poorer than the full parallel search method, but the computational costs are decreased dramatically.
