Abstract
An Uplink Power Control method of adjusting an operating point of a High-Power Amplifier (HPA) of a ground-to-satellite emitter (GWj, GWk, GWl) as a function of propagation attenuation, characterized in that the method includes the steps of: a) determining an optimal Output Back Off value of the High-Power Amplifier which, for an operational propagation attenuation level, maximizes a Signal over Noise plus total interference ratio at the satellite taking into account contributions from cochannel and cross-polar interferences, intermodulation interferences and thermal noise; and b) setting the operating point of the High-Power Amplifier at the optimal Output Back Off value. A ground-to-satellite emitter comprising a High-Power Amplifier (HPA), a control means (PROC) for adjusting an operating point of said High-Power Amplifier by carrying out such a method.
