Claim 11:
12. The electronic device (100) as claimed in claim 11, wherein validate the re-estimated frequencies obtained from the zero-padded version of the received signal based on validation criteria, comprises:
apply a likelihood function on the estimated initial frequencies and the re-estimated frequencies;
determine value of the likelihood function evaluated at the estimated initial frequencies and value of the likelihood function evaluated at the re-estimated frequencies; and
perform one of:
determine a closeness between the estimated initial frequencies and the re-estimated frequencies when the value of the likelihood function evaluated at the estimated initial frequencies is lower than the value of the likelihood function evaluated at the re-estimated frequencies; and
determine the re-estimated frequencies as the optimal frequencies when the value of the applied likelihood function evaluated at the estimated initial frequencies is higher than the value of the likelihood function evaluated at the re-estimated frequencies.
