Abstract
A method for interference estimation and mitigation includes receiving a high-resolution digital signal. The high-resolution digital signal comprises a signal of interest and an interfering signal. An estimate of the interfering signal is generated using a quantizer. The signal of interest is in a quantization noise of the quantizer. An interference-mitigated signal of interest is generated based on a difference of the estimate of the interfering signal and the high-resolution digital signal.
