Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is a widely used technique but its practical implementation sometimes leads to issues related to the synchronization between the transmitter and the receiver. The sampling frequency offset playing a major role in the degradation of the link performance, various solutions have been proposed to cope with this effect. The objective of this paper is to present a simple blind estimation of the offset, calculated on each OFDM symbol and thus only based on the received data. A correction is then applied on the phase of the received signal. Synchronization of the receiver with a phased-locked loop is not treated in this paper. After illustrating this approach for an additional white Gaussian noise channel, a power line communication in an aircraft is envisaged. The architecture of the network is described and a parametric study is carried out to assess the performance of the proposed offset estimator and the phase correction technique.
