<p>Receivers (1,11) like mobile or cordless terminals and mobile or cordless base stations for receiving signals and comprising decision takers (2,12) for taking decisions like selecting antennas in antenna diversity systems (3) or like selecting channels to be used for communication (13) or like synchronisation decisions for synchronisation purposes are improved by providing them with wave analysers (4,14) for analysing at least a part - like a preamble or a pilot - of the received signal and for in response to analysis results supplying control signals to the decision takers (2,12). Such wave analysers (4,14) provide the receivers (1,11) with better quality indicators compared to prior art signal strength indicators and comprise delaying stages (20) for generating control signals representing DC jitter, comparing stages (40) for generating further control signals representing a presence of a non-part-frequency like presences of higher frequencies and lower frequencies, and data slicing stages (70) for generating sliced bits.</p> |
