GPS L1信号的中频数据采集系统设计
Design of Intermediate Frequency Data Acquisition System for GPS L1
摘要
Abstract
To meet the design requirements of front-end module applied for GPS software receiver, a typical application of SE4150L produced by SiGe Semiconductor on GPS receiver RF( radio frequency) front-end single chip IC is introduced. The output signal of front-end IC passes through the universal serial bus( USB), then datum are transferred to upper PC monitor to process, the design of IF( intermediate frequency) data acquisition system for GPS L1 signal is implemented. The double-antenna feature of SE4150L in the system can satisfy the requirements of various application environments, and datum being real-time transferred to PC with high transmission speed is propitious to base band signal processing and analysis.关键词
