Abstract: This paper presents a new algorithm for blind timing offset estimation in cyclic prefixorthogonal frequency division multiplexing (CP-OFDM) systems. The new algorithm allows the use of the simple non-dispersive Maximum likelihood (ML) time and frequency offset estimator in dispersive channels instead of the very complex dispersive ML time and frequency offset estimators. This new algorithm makes use of the data obtained from channel estimator to generate an adequate pulse shape, which reduces the error of the non-dispersive ML estimator significantly. Such adaptive pulse shaping could be used in mobile full-duplex systems where simplicity translates to less power and lighter weight.
