| description | The invention provides a wireless time synchronization method, which relates to the technical field of communication and navigation, and comprises the following steps of: acquiring integral multiple and decimal multiple clock error information by utilizing an interpolation mode in a time comparison process; in the clock calibration process, a local clock is subjected to frequency multiplication, clock difference information and the local clock subjected to frequency multiplication are jointly input into a pulse control module to calculate the adjustment amount of the local clock, then the local clock is adjusted in a timer mode, and finally the calibrated clock is subjected to frequency division to obtain a local input clock. The time synchronization precision is improved; clock calibration is realized through a timer mode, and a crystal oscillator module does not need to be adjusted, so that the hardware complexity is reduced.
本发明提出一种无线时间同步方法，涉及通信与导航技术领域，在时间比对过程利用插值的方式获取整数倍与小数倍的钟差信息；在时钟校准过程将本地时钟进行倍频，将钟差信息与倍频 |
