Abstract
There are provided measures for cell search and synchronization. Such measures may exemplarily comprise acquiring an observation signal for a carrier signal on a carrier which is under consideration for synchronization with a desired cellular system, calculating a power measure of the observation signal, which indicates a received power of said carrier signal, calculating a non-circularity measure of the observation signal, which indicates a non-circularity of said carrier signal, and calculating a ranking measure, which indicates an applicability of said carrier for synchronization with the desired cellular system, based on the calculated power measure and the calculated non-circularity measure.
