To cancel phase noise which causes the bit error rate of OFDM systems degradation, a novel orthogonal-polarization-based phase noise self- cancellation (OP-PNSC) scheme in the polarization dependent loss (PDL) channel is proposed. In the proposed scheme, the orthogonal polarizations are utilized to transmitted orthogonally polarized signals which are added together at the receiver to cancel phase noise. These orthogonally polarized signals transmitted in the same-frequency channel enable that the proposed scheme has the advantages of more efficient in cancelling phase noise and the spectral efficiency (SE) improvement. Considering the realistic wireless channel, the distortion of PDL is investigated and a PDL pre-compensated OP- PNSC (PPC-OP-PNSC) scheme is proposed to mitigate the power imbalance caused by PDL. Then, the signal- to-interference-plus-noise ratio (SINR) and SE performances are analyzed to evaluate the performance of the OP-PNSC scheme. Finally, the numerical results show that the OP-PNSC scheme achieves performance close to that of OFDM system without phase noise in the PDL channel.
