Performance of a novel XCP-OFDM system

This paper proposes an OFDM system that uses circularly polarized waves for improving the system performance. The circular polarization system has the characteristic that it cannot receive waves that are reflected an odd number of times. Using this characteristic, a modified OFDM system that uses cross-handed circular polarization (XCP-OFDM) is proposed. XCP-OFDM gives a much improved system performance due to a reduction of interference caused by reflected waves and interchannel interference. Both theoretical analysis and system simulation results are described.
