A radio apparatus (95), particularly for mobile radio, which makes it
possible
to adjust the signal reception in a predeterminably optimized way is proposed.
The radio apparatus (95) includes a receiver part (1) and an evaluation
unit (5), which controls the sensitivity and/or the signal-to-noise ratio
of the receiver part (1) as a function of a predeterminable signal reception
quality and the actual signal reception. In the event of defective signal reception,
the evaluation unit (5) increases the sensitivity and/or the signal-to-noise
ratio of the receiver part (1), and when signal reception is error-free
for a predeterminable time it reduces the sensitivity and/or the signal-to-noise
ratio of the receiver part (1).
