This paper proposes a new multi-carrier modulation system using polarization orthogonality to mitigate the degradation due to time variation of the propagation channel and frequency offset between transmitter and receiver. The proposed system applies additional orthogonality to the sub-channels to reduce the inter-channel interference (ICI) by exploiting polarization orthogonality. This paper theoretically analyzes the ICI performance and the bit error rate (BER) performance of the proposed system, and shows the ICI for the proposed system is 6dB less than that of the conventional one. Furthermore, in the case of multipath environment when the polarization orthogonality is not ideal, the proposed system is still effective to improve the performance.
