1. An RF receiver comprising
an analog-to-digital converter for converting an analog intermediate frequency band signal to a digital intermediate frequency band signal, wherein the analog intermediate frequency band signal has a plurality of narrow frequency bands of interest each of which contains a particular signal of interest, a plurality of decimation units coupled in cascade for generating a decimated signal, corresponding to the particular signal of interest in one of the plurality of narrow frequency bands, based on the digital intermediate frequency band signal, a signal processing unit for processing the decimated signal, and a bypass path for feeding a bypass signal to the signal processing unit, the bypass signal being either the digital intermediate frequency band signal or an output signal from one of the decimation units which is not the last one of the cascade coupled decimation units, wherein the signal processing unit is adapted to, by processing the bypass signal in parallel with the decimated signal of the last one of the cascade coupled decimation units, detect critical reception conditions in the particular signal of interest in one of the plurality of narrow frequency bands caused by information indicated by the bypass signal from at least one other of the plurality of narrow frequency bands of interest based on the bypass signal and to adapt the processing of the decimated signal in accordance with detected critical reception conditions. |
