Abstract
The invention relates to a method for transmitter power control and a control arrangement employed for transmitter power control. The control arrangement comprises a control element (1) controlled by a control signal, a sampling means (3) for taking samples of a signal from the control element (1). The control arrangement further comprises a detector (4), an adder (5) and a loop filter (6). The adder (5) and loop filter (6) form a controller for receiving a signal which is transmitted by the detector (4) and forms part of a feedback signal for controlling the control element (1). Between the input and output of the controller, the control arrangement comprises a parallel loop which, when being activated, keeps the feedback loop closed when the sample signal is outside the dynamic range of the detector (4). Keeping the feedback loop closed enables transmitter power control without discontinuities.
