Abstract
Methods, systems and devices for interference characterization and excision are described. An example method for wireless communication includes receiving, via an analog prefilter in a first frequency band, a first analog signal comprising a signal-of-interest and an interfering signal, receiving, via the analog prefilter, in an additional frequency band, an additional analog signal, wherein the additional analog signal comprises the interfering signal, generating, based on the additional analog signal, an estimate of the interfering signal, digitizing the first analog signal to generate a first digital signal, canceling the estimate of the interfering signal from the first digital signal to generate an estimate of the signal-of-interest, and demodulating the estimate of the signal-of-interest to generate estimated data symbols.
