Abstract
Digitally encoded data is carried over a first channel between a base station and a plurality of mobiles with the mobiles sharing a second channel for transmission to the base on a contention basis. Proper decoding of the data requires clock syncing at the receiver site. To hasten clock recovery lock time at the base station and improve system throughput, each mobile includes apparatus for monitoring transmissions by the base station and deriving a transmit clock base for the mobile's transmitter therefrom such that subsequent transmissions by the mobiles are all substantially in synchronization.
