提出了一种利用相位噪声盲补偿的高频谱效率相干光正交频分复用系统。利用伪导频代替导频，可以有效地抑制激光相位噪声，同时降低系统开销。仿真结果表明，该伪导频辅助相位噪声补偿方案的性能接近于导频辅助相位噪声补偿方案，但在相位噪声严重的情况下仍能获得更高的频谱效率。
We propose a high spectral efficiency coherent optical orthogonal frequency division multiplexing system utilizing a novel and almost blind phase noise compensation method. With the aid of pseudo pilots instead of pilots, laser phase noise can be suppressed effectively while the overhead of system is reduced successfully. Numerical results show that the performance of the proposed pseudo pilot-aided phase noise compensation scheme can approach that of the pilot-aided counterpart, yet achieve higher spectral efficiency even when the phase noise is severe.
