Claim 1:
2. The method as claimed in claim 1, wherein validating the re-estimated frequencies obtained from zero-padded version of the received signal based on validation criteria comprises:
applying, by the electronic device (100), a likelihood function on the estimated initial frequencies and the re-estimated frequencies;
determining, by the electronic device (100), value of the likelihood function evaluated at the estimated initial frequencies and value of the likelihood function evaluated at the re-estimated frequencies; and
performing, by the electronic device (100), one of:
determining, by the electronic device (100), 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
determining, by the electronic device (100), 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.
