[Abstract]:Since the 21 century, the information technology in the world has been developing with each passing day. In the field of communication, radio communication has been widely used in all aspects of life. Space radio environment is more changeable and complex, so it is very important to ensure the safety of air radio transmission. It is necessary for relevant departments to use advanced radio monitoring technology to monitor radio waves. Nowadays, radio technology is developing rapidly, and software radio technology can already be programmed by software. Signal acquisition and radio wave analysis are realized. Therefore, based on this technology, new ideas and methods are provided for radio monitoring. With the increasing number of mobile phone users, the mobile network is growing. The radio management organization should strengthen the supervision and management of the number and position of the mobile base station, and realize the optimal configuration of the base station. This paper expounds the basic theory of the software radio monitoring technology. A base station monitoring system based on software radio is designed. Firstly, the development status of software radio related technology and the research background and significance of software radio monitoring are briefly introduced. Then, the hardware of base station monitoring system is completed. Part and software system overall scheme design, The hardware design of the system terminal transceiver based on CPLD is carried out according to the actual application requirements of the hardware, and the radio receiving and transmitting of the RF front-end part of the system are realized. In the part of baseband processing, the high speed signal processing and the high speed data processing of the control processing part are discussed. The architecture view and description are designed in the design of the system software platform, and the database of the software platform and the six function modules are designed. The functions of base station detailed parameter monitoring (GIS) presentation, data comparison, statistical report, data query, radio spectrum monitoring and so on are mainly realized. Finally, the system test case design is completed. The platform test of base station monitoring system is carried out, and the test results are analyzed and summarized. The content of this paper is of great significance to base station monitoring, and the monitoring of the number and distribution of mobile communication base stations is completed. The radio management department can accurately grasp the number and distribution of the base station, which is convenient for effective management. The system is easy to carry, reliable and easy to operate, and can greatly improve the supervision ability and technical level of the radio management department to the mobile base station.
