Abstract

An OFDM (Orthogonal Frequency Division Multiplexing) detector both resistant to frequency and time offset is proposed in this paper. The detector combines a modified frequency offset estimation technique based on the one presented by P.H. Moose in [1], with a Minimum Mean Square Error (MMSE) techniques for time offset correction. Results show that the frequency offset estimation can be performed even when the time offset is unknown, within a given interval, followed with correction of the distortion of the received signal caused by the time offset by the means of an adaptive filter.
