摘　　要：结合实际应用中收发信电台的本振往往存在相位噪声的问题,分析了相位噪声对子载波信号的影响,并针对相位噪声引起的子载波间干扰,给出并分析了基于数据共轭映射的干扰消除方法,对该方法的BER性能和PAPR性能进行了仿真,实验结果表明,基于数据共轭映射的子载波间干扰消除方法具有良好的系统性能。The phase noise of transceiver local oscillator and its influence on sub - cartier 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- cartier interference cancellation method based on data conjugate mapping is excellent in system performance.
