Patent ID: 8290100

Claim:
An interference mitigation apparatus, the apparatus configured to process a received signal to recover information, the apparatus comprising: a low-noise amplifier configured to amplify the received signal; a mixer coupled to the low-noise amplifier and configured to mix the amplified received signal with a secondary local oscillator signal; an analog-to-digital converter coupled to the mixer and configured to digitize the mixed amplified received signal to generate a digital signal; an interference sensor and sampler for sensing and sampling a first interference signal to generate a first sub-signal; a digital rotator for rotating the first sub-signal by a rotation frequency to generate a digital reconstructed interference signal; a correlator for correlating the digital reconstructed interference signal with the digital signal derived from the received signal; and an interference control unit for controlling an adjustment to the processing of the received signal based on the digital reconstructed interference signal to mitigate interference in the received signal.
