摘　　要：提出了一种采用GNU Radio技术及与其配套的硬件前端USRP设计和实现GSM900M路测仪的设计方法,配合使用全球定位系统GPS就能够实现采集信号电平、获得信令数据等功能。该系统设备成本低,使用纯软件的信号处理,具有很大的灵活性;采用高级语言进行系统开发,扩展性和可移植性强,开发周期短,降低了系统的维护和升级成本。最后通过实测验证了该系统在实际环境中的可行性和有效性。A design of road tester in the GSM（Global System for Mobile Communications） 900MHz band and by using the USRP（Universal Software Radio Peripheral） and GNU Radio is proposed.Cooperated with GPS（Global Positioning System）,functions such as getting the signal intensity and capturing signaling data could be achieved.With this solution,a low-cost and reliable tester could be made,which is of great flexibility owing to the functions in processing signals.By using high-level language for development,the system is of high scalability,good portability and short development cycle,thus could reduce the system maintenance as well as upgrade costs.Finally,the test in actual environment proves the feasibility and effectiveness of the system.
