摘要
2009年8月ETSI颁布的DRM(Digital Radio Mondiale)标准将调频段DRM数字广播囊括其中,介绍该标准中调频段DRM数字广播的优势与信道部分的技术特性。调频段DRM数字广播通过信道编码技术、信道复用、OFDM调制等技术,实现调频段广播信号的传输,与DAB相比可快速而平滑地实现FM波段广播由模拟向数字的过渡。
The DRM standard promulgated by ETSI in August 2009 adds the specification of DRM Digital broadcasting on FM band. The technical properties of the DRM Digital FM Broadcasting are introduced in this paper. DRM digital broadcast on FM band achieves the transmission of FM broadcast signals by channel coding technologies, channel multiplexing, OFDM modulation technology. Compared with DAB, FM band broadcast can be realized from analog to digitization quickly and smoothly.
