Abstract

A new symbol timing synchronization scheme based on a tailored training sequence is proposed and implemented in direct modulation and direct detection optical OFDM PON (DM-DD OFDM PON) systems. This tailored training sequence is added in front of OFDM data symbols. By using the received signal correlation operation, receiver calculates the peak value of metrics to achieve accurate symbol timing synchronization. The performance of this new timing synchronization scheme is presented by simulation and experiment. The results show that the proposed scheme has high synchronization accuracy and is suit for DM-DD OFDM PON system.
