Abstract
A synchronization device for a terminal of a radio communication system, adapted to identify a control channel constituting one of a plurality of receive channels by means of a receiver (2) comprises means (3) to measure the power of the receive channels and means (4) for attempting synchronization to at least some of said channels identified in a list (5), and is characterized in that, the system being such that a reference channel (C.sub.r) of nominal power (P.sub.r), its ith predecessor (C.sub.r-1) and its ith successor (C.sub.r+1) have an ith attenuation (A.sub.i) when the receiver (2) is tuned to the reference channel (C.sub.r), it comprises selection means whereby the ith predecessor (C.sub.r-i) or the ith successor (C.sub.r+1) do not appear in the list if its power is less than the nominal power (P.sub.r) of the reference channel (C.sub.r) reduced by the ith attenuation (A.sub.i).
