Abstract:
The invention relates to an IF receiver that is able to solve the image band problem and, in particular, to reject any interfering signals so as to ensure correct demodulation of a received useful signal without having to interrupt the reception service. The receiver comprises a monitoring branch configured to monitor interference experienced at a plurality of intermediate frequencies usable in reception and select the intermediate reception frequency from the intermediate frequencies usable in reception on the basis of the interference monitoring carried out. Moreover, the monitoring unit is configured to carry out real-time monitoring of interference experienced at the currently used intermediate reception frequency and also at the other intermediate frequencies usable in reception and change, in real time, the used intermediate reception frequency on the basis of the real-time interference monitoring.
