摘要
Coarse frequency offset estimate and tracking of residual frequency offset are two crucial stages for frequency synchronization in OFDM based WLAN systems. An improved frequency offset estimation scheme is proposed for tracking residual offset, The estimation scheme is dependent on the position of an OFDM symbol in a frame. (C) 2009 Elsevier Inc.
