Abstract
In one implementation, a minimum metric function with an output representing a metric of a satisfaction of transmission requirements for a satellite communications system configured to produce at least two beams may be generated. The minimum metric function may be a function of beam weight parameters including a first and second set of beam weight parameters representing output signals of high power amplifiers used to form a first and second beam, respectively. An output value of the minimum metric function may be calculated using initial values for the beam weight parameters. A direction to modify the values of the beam weight parameters may be determined based on the calculated output value. Updated values of the beam weight parameters may be determined based on maximizing the output value of the minimum metric function by moving the values of the beam weight parameters in the determined direction.
