摘要

摘要:
利用調(diào)頻廣播附加信道作為載波進(jìn)行時(shí)間信息的傳遞為調(diào)頻廣播授時(shí)奠定了基礎(chǔ)，該文基于對調(diào)頻廣播附加信道的研究，提出新的授時(shí)擴(kuò)頻碼設(shè)計(jì)方法并詳細(xì)設(shè)計(jì)了擴(kuò)頻碼內(nèi)容，既符合信道條件要求，又有利于接收端的精確捕獲跟蹤，從而進(jìn)行時(shí)間信息的傳遞并實(shí)現(xiàn)授時(shí)功能，實(shí)測結(jié)果驗(yàn)證了該方法的可行性和準(zhǔn)確性。

Abstract:
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.
