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.
