In this paper, a novel ICI reduction technique, with the combination of RF delay circuit and simple digital signal processing, is proposed. Proposed OFDM is compatible to existing OFDM systems and has 100% frequency efficiency. BER performance of proposed system is analyzed under the indoor multipath channel of 60GHz by computer simulation. Simulation results in LOS multipath channels shows proposed technique enables BER of 1.0E-05 without forward error correction (FEC) for both QPSK and 16QAM modulation schemes under the presence of phase noise and frequency shift.
