This article proposes a nonlinear known-interference (KI) cancellation algorithm that allows a receiver to suppress the interference from a high-power cooperative jammer given that the transmitted interference is known in advance to the receiver. The proposed algorithm achieves this by estimating and compensating for the nonlinear power amplifier distortions, wireless channel effects, and frequency offsets that alter the transmitted interference as it propagates to the receiver. Measurements with commercial off-the-shelf radio platforms in both laboratory and outdoor conditions are presented. Their results demonstrate that the proposed method is able to cancel KI with moderate residuals for a wide range of received signal-to-interference-plus-noise ratio. This facilitates processing a signal of interest that is otherwise masked by the interference signal.
