An Inter-carrier Interference Cancellation Method Based on Data Conjugate Mapping

The phase noise of transceiver local oscillator and its influence on sub-carrier signal are analyzed.Aimed at the inter-sub-carrier interference caused by phase noise,an interference cancellation method based on data conjugate mapping is given and discussed.The performances of bit error rate and peak average power ratio are simulated.The simulation demonstrates that the inter-carrier interference cancellation method based on data conjugate mapping is excellent in system performance.
