Abstract: Self-jamming interference associated with a transmitted signal of an aggressor transmitter may affect a received signal of a victim receiver in a communication device. A victim receiver may obtain a non-linear interference cancelation (NLIC) signal from an aggressor transmitter of a communication device. The NLIC signal may be based, at least in part, on a source transmit signal that has been distorted by digital pre-distortion (DPD) at the transmitter. An NLIC unit may reconstruct a cancelation signal based on the NLIC signal. A receiver may remove the cancelation signal from a received signal.
