Abstract :
In this paper, we propose a frame structure and robust synchronization to realize the cloud transmission (Cloud Txn) system. The proposed frame structure is based on orthogonal frequency division multiplexing (OFDM) for the Cloud Txn system. Also, we study the robust synchronization suitable for the proposed OFDM-based frame structure. Simulation results show that the proposed frame structure and synchronization are feasible for OFDM-based Cloud Txn system under the negative SNR environment.
