| 摘 要： | 文章将原先用于时域均衡中经典的最小均方（LMS）算法与单载波频域均衡技术相结合，提出了使用LMS算法来更新频域均衡器的均衡系数，从而使均衡器的均衡系数根据信道特性自适应地变化。通过仿真验证了LMS算法在频域土毛衡技术中的有效性，并取得了良好的均衡效果。

| Abstract: | In this paper, Least Mean Square （LMS） algorithm, which is originally used in time domain equalization （TDE）, is combined with Single-carrier Frequency Domain Equalization （SC-FDE） technology. LMS algorithm is used to update the weights of adaptive frequency domain equalizer, so that the weights of frequency domain equalizer are adjusted according to channel characters. The simulation results show that the LMS algorithm is suitable for equalizers in frequency domain and could achieve good performance in equalization. |
