Patent ID: 8422971

Claim:
A receiver for a wireless communication device, the receiver comprising: an analog-to-digital converter (ADC) operable to convert an RF signal received at the receiver to a digital signal; and a spur mitigation unit operable to receive an output signal of the ADC, wherein the spur mitigation unit comprises: a growing box filter operable to determine a current estimate of a spur signal of the ADC output signal, and a power measurement unit operable to: determine a power of the current estimate of the spur signal and a power of a previous estimate of the spur signal, determine whether the power of the previous estimate of the spur signal is greater than the power of the current estimate of the spur signal; wherein, if the power of the previous spur signal estimate is greater than the power of the current spur signal estimate, the spur mitigation unit is operable to remove the spur signal from the ADC output signal based on the previous spur signal estimate.
