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 method based on GNU Radio technology and its accompanying hardware front-end USRP is proposed. The design method of GSM900M road test instrument is proposed. With the use of Global Positioning System (GPS), the signal acquisition level and the signaling data can be achieved. The system has the advantages of low equipment cost, pure software signal processing, great flexibility, high-level language for system development, scalability and portability, short development cycle, and reduced system maintenance and upgrade costs. At last, the feasibility and effectiveness of the system in real environment are verified by measurement.
