This paper proposes a XCP-OFDM(orthogonal frequency division multiplexing using cross-handed circular polarization) system that uses circularly polarized waves for improving the system performance. The circular polarization has a characteristic that it cannot receive the reflected waves by odd times. By reducing the influences of the reflected waves, the circular polarization can reduce the time delay spread and the interchannel interference. The proposed XCP-OFDM system divides the subchannels into a right-handed circular polarization (RHCP) channel and a left-handed circular polarization (LHCP) channel that alternate each other. Therefore, the overlap of the subchannel spectrums can be reduced. It means that the orthogonality between subchannels can be improved and as a result it can reduce the interchannel interferences. The proposed XCP-OFDM system can improve the system performance as well as the spectrum efficiency. Both theoretical analysis and the simulation results are described.
