摘 要:根据HFC网络上行信道的特性,建立了信道模型 分析了上行信道中存在的各种噪声对QPSK
调制技术的影响。结果表明在C /N (传输信道载噪比)较低的情况下,采用QPSK调制方式,可以提高系
统的抗干扰能力。

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-Analysis of phase noise on the ortho
