A base station (210, 310, 410) operating with a system clock, the base station comprising: a transmitter configured to send a first radio frequency signal modulated onto a first RF carrier over a first channel to a mobile station (220, 320, 420), the first RF carrier having a first phase and the first channel having a first variable phase delay (Δφ 1), wherein the mobile station (220, 320, 420) is adapted for receiving the first RF signal, recovering the first RF carrier, generating a second RF carrier using the recovered first RF carrier, and synchronizing a local clock using at least one of the recovered first RF carrier and the second RF carrier; a receiver configured to receive a second RF signal modulated onto the second RF carrier over a second channel from the mobile station (220, 320, 420), the second RF carrier having a second phase and the second channel having a second variable phase delay (Δφ 2); a phase error detector (352, 452) configured to determine a phase error signal based on a difference between the first phase and the second phase; the base station being characterized in that it further comprises a controller programmed to: generate a control signal (μ) based on the phase error signal; and apply the control signal to a first inverse channel model (356, 456) having a first function (Δφ 3 (μ)) that approximates an inverse of the first phase delay (-Δφ 1), and to a second inverse channel model (358, 458) having a second function (Δφ 4 (μ)) that approximates an inverse of the second phase delay (-Δφ 2), wherein the approximated inverse of the first phase delay is applied to a subsequent first RF signal sent by the transmitter over the first channel to the mobile station (220, 320, 420), thereby reducing the first variable phase delay of the first channel and the clock phase error at the mobile station (220, 320, 420) resulting from the first variable phase delay. a transmitter configured to send a first radio frequency signal modulated onto a first RF carrier over a first channel to a mobile station (220, 320, 420), the first RF carrier having a first phase and the first channel having a first variable phase delay (Δφ 1), wherein the mobile station (220, 320, 420) is adapted for receiving the first RF signal, recovering the first RF carrier, generating a second RF carrier using the recovered first RF carrier, and synchronizing a local clock using at least one of the recovered first RF carrier and the second RF carrier; a receiver configured to receive a second RF signal modulated onto the second RF carrier over a second channel from the mobile station (220, 320, 420), the second RF carrier having a second phase and the second channel having a second variable phase delay (Δφ 2); a phase error detector (352, 452) configured to determine a phase error signal based on a difference between the first phase and the second phase; the base station being characterized in that it further comprises a controller programmed to: generate a control signal (μ) based on the phase error signal; and apply the control signal to a first inverse channel model (356, 456) having a first function (Δφ 3 (μ)) that approximates an inverse of the first phase delay (-Δφ 1), and to a second inverse channel model (358, 458) having a second function (Δφ 4 (μ)) that approximates an inverse of the second phase delay (-Δφ 2), generate a control signal (μ) based on the phase error signal; and apply the control signal to a first inverse channel model (356, 456) having a first function (Δφ 3 (μ)) that approximates an inverse of the first phase delay (-Δφ 1), and to a second inverse channel model (358, 458) having a second function (Δφ 4 (μ)) that approximates an inverse of the second phase delay (-Δφ 2), wherein the approximated inverse of the first phase delay is applied to a subsequent first RF signal sent by the transmitter over the first channel to the mobile station (220, 320, 420), thereby reducing the first variable phase delay of the first channel and the clock phase error at the mobile station (220, 320, 420) resulting from the first variable phase delay.
