Abstract
An RF receiver is disclosed. The RF receiver includes an analog-to-digital converter for converting an analog intermediate frequency band signal to a digital intermediate frequency band signal. A plurality of decimation units coupled in cascade for generating a decimated signal based on the digital intermediate frequency band signal are also included. The RF receiver further includes 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 is 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. The signal processing unit is adapted to detect critical reception conditions based on the bypass signal and to adapt the processing of the decimated signal in accordance with detected critical reception conditions.
