A study on timing synchronization for MC-CDMA system

摘要

In MC-CDMA system, accurate timing synchronization is very important to improve the transmission quality. In this paper, we propose a high accurate timing synchronization method based on cross correlation techniques which use the replica of pilot signals. The proposed method has a characteristics that consecutive OFDM symbols are added coherently and that the replica is shorter than one OFDM symbol length. Then we clarify that the proposed method can establish timing synchronization with low signal processing.
