摘要	The wireless communication technology is now widely used in many different applications. For example: communication, surveying and mapping, navigation and national defense and other fields. However, the frequency resources of wireless communication are becoming more and more tense, especially the related time service means used for time transmission, satellite time service, short wave time service and other technologies have been very mature. As a new time service method, time transmission using FM broadcasting additional channel will not occupy new frequency resources, nor will it interfere with the original audio broadcasting A very useful technique. In this paper, we propose a new method for transmitting time information through an additional frequency modulation (FM) broadcasting channel, based on the existing FM broadcasting technology. As a result, the transmission and reception technology required is mature and readily available, which makes this approach accessible as well as affordable. A field test was conducted, which demonstrated that the proposed method is feasible and accurate. This method meets the channel conditions and is conducive to accurate acquisition and tracking of the receiving end. This approach is expected to achieve higher accuracy, of sub-millisecond order, than existing methods, which will make it suitable for applications such as regional and battlefield formation time synchronization signal systems.
