Abstract
Embodiments can provide spurs removal in a pilot-tone spread signal. For achieving this, at least one peak in the pilot-tone spread signal may be found. A predetermined small range of the spectra power around the at least one peak may be removed. In some situations, the removal of the spurs in the pilot-tone spread signal may result in inadvertent removal of a normal part of the pilot-tone spread signal. For addressing this, a power ratio between the spectrum of the pilot-tone spread signal before the removal and after the removal can be calculated. For accounting for the power loss due to the spurs removal, this power ratio can be applied to the pilot-tone spread signal after the removal to obtain a corrected pilot-tone spread signal.
