Abstract

This paper proposes a novel none pilot-Assisted orthogonal frequency division multiplexing (OFDM) technology based on multidifferential amplitude phase shift keying (mDAPSK) for optical OFDM system. It doesn't require any bandwidth-consuming pilot tones or training sequence for channel estimation due to the differential detection during demodulation. In the experiment, a 41.31 Gb/s 64DAPSK-OFDM signal without pilot tones is successfully transmitted over 160-km single mode fiber (SMF). The performance comparison between multi-quadrature amplitude modulation (mQAM) and mDAPSK is also given in the experiment, and the results indicate a prospect of this technology in optical OFDM system.
