| 摘要 |
The invention relates to a communication device (2) comprising an antenna system (4) provided with at least one antenna (6a, 6b, 6c) for receiving a radio signal and supplying a received radio signal to an output (8) of the antenna system, a low noise amplifier (10) for amplification of the received radio signal to obtain an amplified radio signal, and a processing unit (12) for processing the amplified radio signal. The antenna system (4) is configured to supply in a first state a first antenna signal as the received radio signal and in a second state second antenna signal as the received radio signal, wherein the first antenna signal and second antenna signal differ in amplitude. The antenna system is further configured to switch from state in response to a control signal (14) generated by the processing unit (12). |
