ABSTRACT:
A method for determining a frequency error over at least one frequency search space for a received signal, the method including the steps of: calculating a first noise estimation for a first frequency offset in a frequency search space; calculating at least a second noise estimation for a second frequency offset in the frequency search space; and determining a minimum noise estimation from the calculated noise estimations, wherein the frequency error is the frequency offset corresponding to the minimum noise estimation.
