<p>A communication unit for use in a communication system, the communication unit characterized by hopping means for hopping a plurality of communication frames over a plurality of carrier frequencies according to a predetermined hopping pattern, at least one of the plurality of communication frames comprising a synchronization channel time slot, the synchronization channel time slot comprising data bits from which the predetermined hopping pattern can be derived. A communication unit for a communication system, the communication unit characterized by: (a) signal acquisition means for initially acquiring a predetermined hopping pattern which specifies the sequence over which a plurality of communication frames are hopped over a plurality of carrier frequencies, the signal aquisition means comprising detecting means for detecting a synchronization channel time slot within a communication frame, the synchronization channel time slot comprising data bits from which the predetermined hopping pattern may be derived; and (b) hopping means, operatively coupled to the signal acquisition means, for hopping a receiving frequency of the signal acquisition means, for hopping a receiving frequency of the signal acquisition means according to the predetermined hopping pattern such that a control channel may be detected.</p> |
