Abstract

This paper deals with the carrier frequency synchronization of orthogonal multicarrier systems, which are an effective transmission technique for coping with the typical channel impairments present in mobile reception. A new carrier frequency detector is introduced and its performance thoroughly analyzed in the presence of a multipath channel. In particular we have analytically derived the frequency detector characteristic curve and its noise power spectral density. We have compared the new algorithm with other known algorithms and we have shown that it permits a considerable improvement in the noise level to be achieved. Therefore the proposed algorithm seems to be a valid candidate for carrier frequency recovery in applications employing multicarrier transmission.
