Abstract :
A simple symbol timing synchronisation (STS) scheme is proposed, based on replica correlation robust to frequency offset in orthogonal frequency division multiplexing systems. The proposed scheme applies a sequence and its modified sequence to total feasible frequency resources used in STS. A comparison is made with the current long-term evolution scheme.
