摘要
In orthogonal frequency division multiplexing (OFDM) systems, the loss of orthogonality between the subcarriers due to carrier frequency offset (CFO) can degrade the performance of the system. In this paper, a residual CFO synchronization method is proposed for ultra wideband OFDM (UWB-OFDM) systems. The proposed. ne frequency synchronization scheme uses a channel estimation sequence and physical layer convergence protocol (PLCP) header information which are equipped with frequency-domain spreading. A UWB-OFDM receiver with algorithm for. ne frequency error synchronization is simulated and is evaluated in terms of mean square error.
