Abstract

The invention relates to an adaptive radio receiver apparatus suitable for use in a base station or a mobile telephone in a telecommunication system or a telecommunication system having radio in the local loop. The radio receiver is controllable for optimising operating parameters of the amplification circuits included in the receiver, in dependence of the traffic situation in which the receiver is located. The radio receiver in accordance with the invention utilises controllable amplifiers and adaptive control logic for controlling the operating parameters. The receiver apparatus comprises at least one controllable amplifier stage which is under control from a control unit for varying the operating parameters of the amplifier stage in dependence of the environment. The amplifier stage preferably includes a controllable low noise amplifier and a variable attenuation attenuator. Preferably the receiver apparatus has the capacity of controlling the operating parameters such as the blocking level, the intercept level, the sensitivity, the noise figure, the power consumption and the gain. The control unit comprises control logic for forming combinations of the operating parameters, each combination corresponding to a specific traffic situation.
