摘要
主要研究了影响数字调幅(Digital Amplitude Modulation,DAM)中波发射机信噪比的主要因素和相应的对策.首先介绍了数字调幅广播的工作原理和DAM中波发射机信噪比(Signal-to-Noise Ratio,SNR)的基本概念,其次重点分析了影响DAM中波发射机信噪比的主要因素,最后针对性地提出了抑制其影响的措施,以期为改进DAM中波发射机性能提供参考.
Abstract
This paper mainly studies the main factors affecting the signal-to-noise ratio of Digital Amplitude Modulation(DAM)medium wave transmitter and the corresponding countermeasures.Firstly,the working principle of digital AM broadcasting and the basic concept of Signal-to-Noise Ratio(SNR)of medium-wave transmitter in DAM are introduced.Secondly,the main factors affecting the SNR of medium-wave transmitter in DAM are analyzed emphatically.Finally,the measures to restrain its influence are put forward,which provides reference for improving the performance of medium-wave transmitter in DAM.
