Data Acquisition and Processing Technique for Software GPS Receivers

摘要：

Recent advancement in digital signal processing and analog-to-digital conversion techniques has driven the use of software radioInradio frequency signal receiving.This paper applies the concept of software radio to GPS signal acquisition and tracking.GPS signal receiver consists of RF front-end,buffer memory,and a digital signal processor.In comparison with traditional approaches,the software radio structure has many advantages such as programmability and flexibility.In this paper,GPS acquisition and tracking algorithms are designed and developed. The simulation results show that this technique can improve the whole performance of GPS receivers and can provide the experiment platform with the design and development of kinds of the new algorithms and ideas for enhancing GPS receiver performance.
