基于射频数字化的中短波广播监测系统探究

Exploration on Medium Short Wave Radio Monitoring System Based on RF Digitalization

近年来通信和广播等方面的快速发展,使中短波频谱被占用、频道受干扰的问题日益严重,中短波广播在传播、建设、使用等方面的优势难以充分发挥,为有效利用中短波频谱,降低频道之间的干扰,人们尝试建立中短波广播监测系统并应用射频数字化相关技术,使中短波广播信号异地接收、存储、还原等成为可能。文章对基于射频数字化的中短波广播监测系统产生较全面的认知,在对中短波广播信号射频数字化理论基础和现阶段中短波广播监测系统架构进行系统分析的基础上,对基于射频数字化的中短波广播监测系统架构展开研究。

In recent years the rapid development of communication and broadcast, etc, make the medium short wave spectrum occupied, channel interference problem is increasingly serious, medium-wave radio in transmission, construction, use and other aspects, it is difficult to give full play to the advantages of for intermediate frequency spectrum efficiency, reduce the interference between channels, people try to establish medium-wave radio monitoring system and application of radio frequency digital correlation technology, make long-distance medium-wave radio signal receiving, storage, reduction, etc. Articles on medium-wave radio monitoring system based on rf digitalization of cognition, the theoretical basis of medium short wave radio signal rf digitalization in and the present stage medium short wave radio monitoring system architecture on the basis of system analysis, the medium short wave radio monitoring system based on radio frequency digital architecture study.
