Abstract
Combining with data acquisition and virtual instrument, this paper makes a design of demodulation system with software radio technology, by using G language and LabVIEW IDE. Based on demodulation and analysis on AM and FM signal collected by data acquisition card, and modulated signal in local machine, a pulse mean marker filtering algorithm is proposed to demodulate FM signal. Besides that, the soft radio system has some other functions such as printing and saving real-time signal, playback of historical signal. The soft radio system designed in this paper shows the superiority of data acquisition technology and virtual instrument technology in the radio domain.关键词
