A New Approach for Pulsed Pseudolite Signal Acquisition Using FFT

摘要：

This paper investigates the acquisition of pulsed pseudolite signal.We present the model of pulsed pseudolite signal.Based on a specific pulse pattern,performance of the serial pulse acquisition method is analyzed,and its indicated that the prime disadvantage of this method is the long acquisition time.To solve this,we propose a new pulse acquisition method using FFT,and the model of this method is given.Then we focus on the segmentation question and the pulse truncation question in FFT acquisition method.Software simulation indicates that short segment length and pulse truncation detecting algorithm can effectively improve the performance of FFT pulse acquisition method.
