Abstract:
A processing device (60) for a radio-receiver circuit (20) is disclosed. The radio-receiver circuit comprises an input terminal (22) for receiving an analog input signal, circuitry (50) for generating a compensated analog input signal by subtracting an analog compensation signal from the analog input signal, an analog-to-digital converter (30) arranged to receive the compensated analog input signal on an input terminal of the analog-to-digital converter (30), and circuitry (40, 110) for to generating the analog compensation signal based on a digital compensation signal. The processing device (60) comprises: an input terminal (62) for receiving an output signal of the analog-to-digital converter (30); and an output terminal (64) for supplying the digital compensation signal. The processing device (60) is adapted to: generate an estimate of a blocking signal component in the analog input signal of the radio receiver circuit (20) based on the output signal of the analog-to-digital converter (30); and generate the digital compensation signal based on said estimate such that said blocking signal component is at least partially cancelled in the compensated analog input signal. Embodiments of radio receiver circuit, integrated circuit, electronic apparatus, method, computer program, computer readable medium and hardware-description entity are also disclosed.
