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).
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, comprising means to measure the power of said receive channels and means for attempting synchronization to at least some of said channels identified in a list, said system being such that a reference channel of nominal power, at its i-th predecessor and its i-th successor, has an i-th attenuation when said receiver is tuned to said reference channel, and further comprising means for eliminating from said list said i-th predecessor when the power thereof is less than the nominal power of said reference channel reduced by said i-th attenuation and for eliminating from said list said i-th successor when the power thereof is less than the nominal power of said reference channel reduced by said i-th attenuation.
A method of synchronizing a terminal to a base station of a radio communication system comprising:
