摘要 将基于二项式消除编码(PCC)的子载波间干扰(ICI)自消除方法与基于导频的公共相位误差(CPE)纠正以及最小均方误差(MMSE)均衡方法相结合,抑制OFDM系统的相位噪声。仿真结果表明,无论在高斯信道还是多径瑞利衰落信道下,本方法都可以有效抑制OFDM系统的相位噪声,同时实现复杂度低,具有较好的实用性。 The Inter Carrier Interference （ICI） self-canceling based on Polynomial Canceling Code （PCC） is combined with the correction of Common Phase Error（CPE） based on pilot and Minimum Mean Square Error（MMSE）. This method is introduced to sup- press the phase noise of the OFDM system. The simulation results show that the method can suppress the phase noise of OFDM system effectively over gauss channel or muhipath rayleigh fading channel. It also has low complexity and good practicability.
