Claim 5:
6. The method as claimed in claim 4, wherein the iterative filtering comprises:
determining, by the electronic device (100), a subset of at least one re-estimated frequencies as optimal sinusoids;
removing, by the electronic device (100), the determined optimal sinusoids from the received signal;
re-estimating, by the electronic device (100), frequencies of the remaining sinusoids of the received signal;
combining, by the electronic device (100), the determined frequencies and re-estimate frequencies of the remaining sinusoids;
applying gradient, by the electronic device (100), using the combined frequencies set as the initial guess;
exhaustively, by the electronic device (100), cycle through all possible subsets of frequencies; and

determining, by the electronic device (100), final estimate based on likelihood function evaluation.
