Abstract
A method for providing power control to a uplink signal, comprising an uplink station transmitting an uplink signal to a satellite. The satellite also transmits a loopback signal representing the received uplink signal back to the uplink station. The satellite also transmits a beacon signal to the uplink station. The uplink station adjusts the power of the uplink signal based on measurements of the beacon signal and the uplink signal.
Claims34
A system for providing performance control of a first signal transmitted by a first station to a second station, comprising:
- a means for measuring a performance parameter of a second signal that is transmitted to the first station from the second station;
- a means for measuring a performance parameter of a third signal that is transmitted to the first station from the second station and is representative of the first signal as received by the second station;
- a means for performing a first adjustment to the power of the first signal in response the performance parameter of the second signal;
- and
- a means for performing a second adjustment to the power of the first signal in response the performance parameter of the third signal.
