Abstract
In order to acquire the B2a signal of Beidou-3 quickly and accurately,an acquisition algorithm based on PMF-FFT is proposed.Firstly,the characteristics of PMF-FFT algorithm are analyzed by establishing mathematical model.Then,the selection of pa-rameters such as PMF segment length,FFT operation points,correlation integration time,incoherent integration times and decision threshold are analyzed in detail.Finally,Matlab is used to simulate and analyze the performance of PMF-FFT acquisition algorithm,which verifies the effectiveness of the algorithm and solves the primary problem for the implementation of the algorithm.关键词
