Frequency offset, CRB, fading channels.
The sample autocorrelation function has historically
played a big role in determining the frequency offset in
the AWGN environment. Most estimators available in
the literature have some kind of combination of this
function. Although, some analysis has already been
done in the flat fading case, in this correspondence, we
take a simplistic different view of the effects of this
particular communication environment on the frequency
estimation via the sample autocorrelation function.
Comparisons with the AWGN case are also given.
