The invention relates to a system and method for receiving radio frequency signals. The system comprises a plurality of front-end receiving units, a processing unit, and a bus system coupling the front-end receiving units to the processing unit. The front-end receiving units are coupled to antennas for receiving radio frequency signals and are arranged for demodulating and digitizing the received radio frequency signals to digitized demodulated signals. Furthermore the front-end receiving units are arranged for transmitting the digitized demodulated signals to the processing unit. The processing unit is arranged to generate an output signal either in dependence on a combination of the digitized demodulated signals or in dependence on a selected digitized demodulated signal. Preferably the digitized demodulated signal with the best quality signal is selected. For this purpose the front-end receiving units are arranged to generate the quality signal in dependence of the received RF-signal, while the processing unit is arranged to select the front-end receiving unit, providing the quality signal representing the radio-frequency signal with the best quality, to transmit the digitized intermediate signal. |
