ABSTRACT:
A receiver circuit for a mobile radio receiver has a controllable amplifier with a variable gain level, an analog-digital converter stage, a digital filter configuration for the purpose of channel selection and a signal strength estimator. The signal strength estimator is connected downstream of the filter configuration in the signal path and has the purpose of determining the signal strength in the selected user signal. The amplifier is controlled in dependence on the user-channel signal strength determined by the signal strength estimator.
