Özet

This paper proposes a novel frequency-domain channel estimator which mitigates the effects of ICI by jointly finding the frequency offset and channel frequency response (CFR). A binary search algorithm is used to find the present frequency offset and CFR jointly. The variance of the jointly estimated frequency offset is found to be very close to the Cràmer-Rao lower bound.
