Abstract
In mobile radio receivers, the transmission power must be raised before the start of the transmission process, and must be reduced again after the end of the transmission process. Until now, the transmission power has been controlled exclusively by varying the gain of the power amplifier. The inventive concept is based on using a scaling unit to additionally scale the amplitudes of the baseband signals in order to assist the switching-on and switching-off processes.
