摘要

正交频分复用(OFDM)是实现高速无线传输的一项重要技术。本文采用一种称为步长δ最小均方(SSD-LMS)的方案来消除相位误差。结果表明，与传统LMS算法相比，SSD-LMS算法收敛速度快，稳态波动误差小。

Phase Error Cancellation for OFDM Systems Using Adaptive Filters

Orthogonal Frequency Division Multi-plexing (OFDM) is a significant technology to provide a high-rate wireless transmissions. In this paper, a scheme called as a step size delta - least mean square (SSD-LMS) is used for phase error cancellation. The results show that SSD-LMS algorithm can provide a rapid convergence with a low steady-state fluctuation error than that with the conventional LMS algorithm.
