Abstract

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.
