A base station operating with a system clock includes a transmitter, a receiver, a phase error detector and a controller. The transmitter sends a first RF signal modulated onto a first RF carrier having a first phase over a first channel having a first variable phase delay to a mobile station. The mobile station recovers the first RF carrier, generates a second RF carrier, and synchronizes a local clock using the recovered first RF carrier and/or the second RF carrier. The receiver receives a second RF signal modulated onto the second RF carrier having a second phase over a second channel having a second variable phase delay. The phase error detector determines a phase error signal based on the first and second phases, and the controller generates a control signal based on the phase error signal. The control signal is applied to first and second inverse channel models.
