| 摘 要： | 相位噪声也能引起信道间干扰( ICI) ,本文系统的分析了采用ICI自消除方案前后相位噪声对OFDM系统的影响,得出了载波干扰比和信噪比的近似计算公式,在AWGN信道上仿真了系统的误码性能。从仿真结果看,ICI自消除的方案能够显著提高系统的载波干扰比和误码率

| Abstract: | The phase noise can also cause the inter sub-carrier interference(ICI),the effects of phase noise were analyzed in OFDM systems with or without the ICI self-cancellation scheme ,derived the approximate calculation formula of carrier to interference ratio(CIR) and signal noise ratio(SNR) and the BER performance was also simulated on AWGN channel. The simulation results demonstrate the ICI self-cancellation scheme can obviously improve the CIR and bit error ratio. |
