相位估计是相干光正交频分复用（CO-OFDM）接收机中的使能功能之一。在这封信中，我们比较导频辅助和数据辅助相位估计方法的CO-OFDM传输实验在8 Gb/s超过1000公里的标准单模光纤没有光色散补偿。我们还表明，少至五个子载波就足以进行导频辅助相位估计
Phase estimation is one of the enabling functionalities in coherent optical orthogonal frequency-division-multiplexing (CO-OFDM) receivers. In this letter, we compare pilot-aided and data-aided phase estimation methods for a CO-OFDM transmission experiment at 8 Gb/s over 1000-km standard single-mode fiber without optical dispersion compensation. We also show that as few as five subcarriers are sufficient for pilot-aided phase estimation
