Performance Comparison of Blind Symbol Timing Estimation in Cyclic Prefixed OFDM Systems

In this paper, an estimated weighting factor and two symbol timing estimators are proposed for timing synchronization of cyclic prefixed OFDM systems. The performance of the proposed estimators is assessed through computer simulations, and compared with that of the van de Beek´s estimator and Muller´s estimator. Experiments demonstrate that one of the proposed estimators outperforms Muller´s and yields a similar performance van de Beek´s but without requiring the priori knowledge of signal and noise powers.
