基于广义延拓逼近的GPS卫星信号多普勒频移估计方法
Doppler shift estimation method of GPS satellite signals based on generalized extended approximation
摘要
Abstract
The picket-fence effect of Doppler shift when the parallel code phase is utilized to capture the GPS satellite signal is studied.In order to reduce the influence of picket-fence effect and improve the acquisition precision of Doppler shift,a generalized extended approximation method is proposed to improve the estimation accuracy of Doppler shift. The method is optimized while maintaining the algorithm computation amount to further reduce the impact of noise on the acquisition accuracy of Doppler shift. The simulation results verify that the method is effective.关键词
