Synchronization is a challenging issue in vehicle-to-everything (V2X) cellular communication, especially when V2X devices need to directly communicate with each other outside the network coverage area. By adopting the maximum likelihood principle, we

An effective integer carrier frequency offset (IFO) detection scheme is proposed in the long-term evolution downlink system without relying on the knowledge of the cell ID (CID) that is carried through the synchronization signal. To enable IFO detect
