摘　　要：利用调频广播附加信道作为载波进行时间信息的传递为调频广播授时奠定了基础,该文基于对调频广播附加信道的研究,提出新的授时扩频码设计方法并详细设计了扩频码内容,既符合信道条件要求,又有利于接收端的精确捕获跟踪,从而进行时间信息的传递并实现授时功能,实测结果验证了该方法的可行性和准确性。Use of FM radio of additional information channel as a carrier lays a solid foundation for time pass for FM radio. Based on the research of FM radio additional channels, a new design method of time-sharing spread spectrum code is proposed and the content of spread spectrum code is designed in detail. It not only conforms to the requirements of the channel conditions, but also is helpful for accurate tracking capture at the receiving end, and for the time information transmission and timing functions. The measured results show the feasibility and accuracy of the method.
