Abstract:
In this letter, a low-complexity phase noise compensation scheme based on Kalman filtering theory is experimentally demonstrated for coherent optical orthogonal frequency-division multiplexing (CO-OFDM) transmissions. The proposed scheme can operate in two modes, pilot-aided mode and blind mode, resulting in a variety of phase noise tracking configurations upon particular transmission scenario. At a bit error rate of 3.8×10-3 and for 40 GBaud 16-QAM 64 subcarriers CO-OFDM systems, the proposed method operating in the pilot-aided mode reduces the pilot overhead by a factor of 2 in comparison with the conventional pilot-aided scheme, while in the blind mode, our scheme's complexity is far superior to one of the state-of-the-art computational efficient decision-direct-free blind approach by a factor of 20.
