Different subscriber units (14) transmit different burst signals to a base station (12) on a common frequency to which a base station demodulator (64) is already synchronized. The base station (12) transmits constant values .alpha. and .eta., where .alpha. is multiplied by a base station reference frequency to achieve a base station transmitting frequency, and .eta. is multiplied by the reference frequency to achieve the base station (12) receiving frequency. A subscriber unit (14) synchronizes to the base station transmitting frequency. As a result of the synchronization process, the subscriber unit (14) determines a value .mu., which, when multiplied by a subscriber unit reference frequency, achieves the subscriber unit synchronization frequency. The subscriber unit then determines a value .gamma., which is proportional to .eta. and .beta. and inversely proportional to .alpha.. The subscriber unit reference frequency is multiplied by .gamma. to achieve the frequency at which the subscriber unit (14) transmits.
