摘要
TFM(可控调频)是近几年发展起来的一种新的调频体制.此技术的最大优点是信号功率谱主瓣窄,频带利用率高,邻道干扰小,又可获得最好的数字传输质量,这是一般调频技术所无法比拟的,本文详细论述了TFM技术的工作原理,实现方法.
Tamed frequency modulation is a new expanded M system in recently years. The system is noted for its narrow signal power spectrum. High avilability frequency band, small adjacent- channel interference and optimum transmission performance. The system is advantage over other FM styles. This paper discuss the working principle and achieving method of TFM.
