1. A method of operation of a wireless communication system comprising:

  • filtering a composite input from a radio frequency signal;

    developing a raw stream based on applying an analog correction to the composite input including removing an interference image from the composite input by an analog cancellation amplifier;

    developing an extracted signal based on sampling the raw stream with a primary analog-to-digital converter;

    generating a digital control based on monitoring the extracted signal with a correction control block; and

    adjusting the analog correction and a digital residue, at the output of the primary analog-to-digital converter, based on the digital control generated using the extracted signal and fed back from the correction control block.
