基于PMF-FFT的高动态长伪码捕获实现
Realization of High Dynamic Long PN Code Acquisition Based on PMF-FFT
摘要
Abstract
Aiming at the problem of high dynamic long PN code acquisition in spread spectrum system,a realization method of ac⁃quisition based on Partial Match Filter-Fast Fourier Transform (PMF⁃FFT) is proposed.The principle of PMF⁃FFT and the acquisition process based on PMF⁃FFT are introduced,and the hardware platform design including the selection of FPGA and board design is given. The algorithm implementation in FPGA is explicated, and the algorithm optimization, operating principle, parameter selection and process design are explained. Matlab simulation result indicates that the acquisition method based on PMF⁃FFT achieves good acquisition probability.Finally the performance measurement result is given and the result is consistent with the simulation result.关键词
