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
symbol in a frame. While the conventional null subcarrier based methods estimate the offset by a single global search, the
proposed method employs a two stage estimator, which greatly minimize the computational complexity.
