A time division multiple access digital communications system (

12

) is provided. The system (

12

) has a base station (

14

) configured to generate a receive baud clock (

86

) and has a receiver (

18

) and a transmitter (

20

). The system also has a subscriber unit (

16

) configured to generate a transmit baud clock (

50

), and has a transmitter (

28

) and a receiver (

26

). The subscriber unit transmitter (

28

) is configured to transmit a reverse channel signal (

54

) that incorporates the transmit baud clock (

50

) as a component thereof. The base station receiver (

18

) is configured to receive the reverse channel signal (

54

) from the subscriber unit (

16

) and produce a phase-error signal (&mgr;′) in response to a phase difference between the transmit baud clock (

50

) and the receive baud clock (

86

). The base station transmitter (

20

) is configured to transmit the phase-error signal (&mgr;′) to the subscriber unit receiver (

26

). The subscriber unit transmitter (

28

) contains an interpolator (

122

) configured to adjust the phase of the transmit baud clock (

50

) in response to the phase-error signal.
