Abstract:
Apparatus for transmitting a first signal having a power level which is indicated by a second signal, the second signal being received by the apparatus, the apparatus comprising:a mechanism for feeding a version of the first signal back to the apparatus via a feedback signal path; feedforward gain control circuitry operatively coupled in a feedforward signal path of the apparatus, the feedforward gain control circuitry being responsive to the version of the first signal for changing the power level of the first signal; feedback gain control circuitry operatively coupled in the feedback signal path, the feedback gain control circuitry being responsive to the version of the first signal for changing a gain of the version of the first signal fed back to the apparatus; and a controller operatively coupled to the feedforward gain control circuitry and feedback gain control circuitry, the controller being responsive to the second signal for imparting a selected gain to the version of the first signal to control the power level of the first signal.
