代码说明：

说明：分析了相位噪声对正交频分复用(OFDM)系统的影响,发现相位噪声不仅产生通用相角错误(CPE),而且还会产生载波间干扰(ICI),这都使OFDM系统的性能急剧恶化,因此必须对CPE和ICI进行校正.文中给出了基于MSE准则的CPE校正方法,考虑到 ICI干扰主要来源于相邻信道,进而提出了基于LMS法则的自适应相邻信道干扰消除方法.整个算法简单高效.仿真结果表明,所提出的算法大大改善了OFDM系统的性能(Phase noise is analyzed for orthogonal frequency division multiplexing (OFDM) systems, the influence of found that phase noise is not only a common phase error (CPE), but also produces the intercarrier interference (ICI), which makes the performance of OFDM system has evil, so must to CPE and ICI. CPE correction method based on MSE criterion are also given in this paper, considering the ICI interference is mainly from the adjacent channel, then was proposed based on the laws of LMS adaptive adjacent channel interference elimination The simulation results show that the proposed algorithm greatly improves the performance of OFDM system)
