Abstract

Time synchronization is purposed to make the different time realizations of many objects as same as possible. As an initial study on time synchronization, this paper proposes a wireless time synchronization method utilizing SDR (Software Defined Radio). For the purpose, reference pulses are generated and transmitted by a reference USRP (Universal Software Radio Peripheral) based on GNU Radio. The other USRPs are synchronized to the reference pulses for time synchronization. To evaluate the accuracy of the proposed method, sampled data and synchronization error of each slave USRP are compared.
