Abstract :
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 the authors have analytically derived the frequency detector characteristic curve and its noise power spectral density. They have compared the new algorithm with other known algorithms and have shown that it permits a considerable improvement in the noise level to be achieved
