摘　　要：2013年国家新闻出版广电总局颁布了调频频段数字音频广播系统的信道标准和复用标准,标志着中国调频频段模拟广播数字化技术已经确定。主要介绍了调频频段数字音频广播系统的相关技术及其传输性能,并结合实验室的测试结果讨论了调频频段数字音频广播的覆盖和干扰问题。The SPPARFT promulgated the channel encodingstandard and multiplex standard of digital audio broadcasting in FM - band in 2013. It demonstrates that Digital technologyof analogy FM broadcasting has been determined in China. We in- troduce the transmission performance and some features of this system. Some questions about the interference and coverage of this system are also discussed according the laboratory testing results.
