Phase Error Cancellation for OFDM Systems Using Adaptive Filters

Abstract

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.
