Decision-directed fine synchronization for coded OFDM systems Conference Paper

abstract

• A new decision-directed (DD) synchronization scheme is proposed for joint estimation of carrier frequency offset (CFO) and sampling clock frequency offset (SFO) in coded orthogonal frequency division multiplexing (OFDM) systems. By exploiting the decisions provided by a Viterbi decoder and the information available on all the modulated subcarriers, we report accurate estimators of residual CFO and small SFO without relying on pilots. The performance analysis and simulation results indicate that the proposed novel DD scheme achieves much better performance than the conventional pilot-based schemes in both AWGN and frequency-selective channels.
