摘      要：Laser linewidth is the important determinant of applying coherent optical orthogonal frequency division multiplexing （CO-OFDM） in optical transmission systems. The laser linewidth impairments in 100-Gb/s polarization division multiplexing CO-OFDM （PDM-CO-OFDM） system without optical dispersion com- pensation are compensated by the phase drift compensator （PDC） based on Mth-power-law method located at the receiver. PDC is more effective to compensate the phase drift due to laser linewidth. Simulating results show that the maximum Q factor can be increased by almost 〉10.0 dB for bemk-to-back （BtoB）. For the 100-kHz linewidth system of 800-km system, a benefit of about 4.9 dB is possible for the maximum Q factor.
