- 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

- 为了使数字信号在有限带宽的高频信道中传输，必须对数字信号进行载波调制。就频带利用率和抗噪声性能（或功率利用率）两个方面来看， QPSK系统最佳。QPSK是利用载波的四种不同相位差来表征输入的数字信息，是四进制移相键控（QPSK）。本项目用MATLAB软件对四进制移相键控信号在AWQN信道中传输进行了建模和仿真，通过对仿真得到的误码率和理论误码率进行比较和分析，从而证明了MATLAB软件仿真QPSK调制解调的可行性。-In order to make the digital signal in t
