Patent ID: 8494100

Claim:
A processing device for a radio-receiver circuit including an input terminal for receiving an analog input signal, circuitry for generating a compensated analog input signal by subtracting an analog compensation signal from the analog input signal, an analog-to-digital converter arranged to receive the compensated analog input signal on an input terminal of the analog-to-digital converter, and circuitry for generating the analog compensation signal based on a digital compensation signal, wherein the processing device comprises: an input terminal for receiving an output signal of the analog-to-digital converter; and an output terminal for supplying the digital compensation signal; and the processing device is adapted to: generate an estimate of a blocking signal component in the analog input signal of the radio-receiver circuit based on the output signal of the analog-to-digital converter a number of steps ahead using an auto-regressive prediction model to account for an inherent delay in one or more components of the radio-receiver circuit; and generate the digital compensation signal based on the estimate such that the blocking signal component is at least partially cancelled in the compensated analog input signal.
