Abstract:
Method for improving the wanted signal in a radio receiving unit having a channel filter (BF2), having a switch (S), having a control unit (SE), having a signal-strength detection unit (RSSI) and having controllable amplifiers (RV1, RV2), characterized in that the control unit drives the switch (S) in such a manner that the switch (S) alternately supplies a first signal (S1) upstream of the channel filter (BF2) and a second signal (S2) downstream from the channel filter (BF2) to the signal-strength detection unit (RSSI), and that the output signal of the signal-strength detection unit is supplied to the control unit, and that the amplifiers (RV1, RV2) are driven as a function of the output signal.
