Network Synchronization for Mobile Device-to-Device Systems [PDF]

IEEE Transactions on Communications, 2017
This paper studies the synchronization problem for mobile cellular device-to-device (D2D) networks. Depending on the number of devices that are in coverage of the base station, the D2D environment can be divided into three categories where the partial-coverage and out-of-coverage are challenging scenarios and thus are the focus of this paper. First, we
