RADIO REPEATER

摘要

A radio repeater for selectively amplifying different time-slots in a radio signal carrying synchronisation data comprises a radio receiver (1) for receiving incoming radio signals; a plurality of amplifying paths (2a, 2b) for amplifying the radio signals received by the radio receiver; a switching means (3) for selectively switching the incoming radio signals to individual amplifying paths from amongst the plurality of amplifying paths; means (4) for monitoring the incoming radio signals; data extraction means for extracting, from the output of the monitoring means, synchronisation data carried by the radio signals; and control means for controlling the switching means (3) in response to the synchronisation data extracted by the data extraction means. This arrangement allows the switching to be controlled by data carried by the signal, without decoding and recoding the signal which is to be transmitted, thereby avoiding the delay caused by such coding/decoding.
