摘要
随着硬件数字化采样技术、光纤通讯技术、下变频技术、计算机硬件处理技术及软件无线电技术的发展,使得中短波广播射频信号数字化处理后进行远距离传输,实现异地接收、存储成为可能,然后再经过信号重构,从而还原历史的中短波广播信号。本文针对现有的中短波广播远程监测系统进行研究探讨,提出了基于射频数字化的中短波广播远程监测系统的架构,希望对目前的中短波广播远程监测系统构架有一定的帮助。
With development of hardware digital-sampling technology, optical fiber communication technology, frequency conversion technology, computer hardware technology and software radio technology, processed MW and SW radio signals' long distance transmission, remote receiving and storing could be realized. By signal reconstruction, it is possible to return to the historical MW and SW radio signal. This paper focuses on research of the existing remote monitoring system of MW and SW radio, and proposes a framework of MW and SW radio monitoring system based on RF digitalization, it is helpful to the current remote monitoring system of MW and SW radio.
