摘　　要：在调频频段数字音频广播关键技术的基础上,调幅波段CDR标准草案也已经初步形成。介绍了中波波段信号传输模型,以及此标准草案中定义的信道编码与调制技术的实现概况。在此基础上,重点介绍了外场测试收测条件及相关的收测数据,并得到相关结论。Based on the Digital Audio Broadcasting in FM-band system, the draft standard of the system in AM -band has been finished preliminarily . The signal transmission model of the signal in AM -band is introduced, and also the channel encoding and modulation technology defined in the draft standard. Besides that, the test conditions and test data of the out -field test are emphatically introduced with the conclusions attached.
