## However, in practice, a residual CFO remains at the receiver after CFO estimation, where the estimation accuracy depends primarily on the fractions of time and power used by the estimator.

Communications2001View PDFCiteSaveAbstract—Orthogonal frequency-division multiplexing (OFDM) is sensitive to the carrier frequency offset (CFO), which destroys orthogonality and causes intercarrier interference (ICI). Using the approach of[6] and our notation, this SNR degradation in decibels can beexpressed as(21)Note that this approximation is derived usingwhich holds for .
