摘要
随着数字广播卫星和高速数字信号处理器技术的发展,采用卫星传输节目源信号已成为实现调频同步广播、扩大广播电台覆盖范围的一种简捷、可行的技术方案。介绍了采用卫星传输节目的调频同步广播系统的工作原理、系统构成及实施时要注意的问题。
With the development of digital satellite broadcasting and high speed digital signal processing technology, adopting satellite transport program signal has become a simple and feasible technology method to realize FM radio synchronous broadcasting and extend the covering of radio broadcast. This article introduces the theory of FM radio synchronous broadcasting system with satellite transporting as well as it＇s system construction and the problems needed to be noticed.
