A Review of MW Simulcasting and an Approach to Synchronizing Technique

本文回顾了实施中波同步广播的经历，分析了目前运行中的同步网所存在的问题。笔者根据１０余年参与同步广播运行管理、科研的体会，论述了实施良好同步广播的措施。就同步广播的发展；标频传送、同步激励的性能及同步网的管理三个关键方面，提出了探讨性的建议和意见。

This paper reviews the history of implementing MW simulcasting and analyses operating problems of today's simelcasting networks. With the over ten yeas' experience on management and research work of simulcasting,the author mentions the methods by which simulcasting will be able to be on well. In the last of the paper,the suggestions on the three vital aspects,including pilot transmission,runction of synchronizing exciter and management of simulcasting network,are made.
