A semi blind technique for estimating the carrier frequency offset in OFDM communication systems is presented in this paper. The fractional and integer frequency offsets are esti-mated by employing a few null subcarriers in the rst OFDM sy

Multicarrier modulations attract a lot of attention ranging from wireline to wireless communications compared to single carrier modulation because of theirs capability to efficiently cope with frequency selective fading channels. Much of attentio
