Non-linear interference cancellation with multiple aggressors
Abstract:
Disclosed is non-linear interference cancellation (NLIC) on a victim receiver in a communication system in which there is self-jamming interference from multiple aggressor transmitters. The victim receiver may implement cascaded NLIC operations using multiple interference signals in succession to remove the multiple interference signals from the Rx signal and to cancel or mitigate the self-jamming interference. The reconstruction and removal of the interference signals may be ordered based on the expected level of interference from the interference signals on the desired Rx signal. The victim receiver may first perform NLIC operation using the Tx signal from the transmitter aggressor estimated to generate the strongest interference signal to remove the strongest interference signal from the Rx signal first. The victim receiver may perform NLIC operation on the TX signal from the next strongest transmitter aggressor, and so on, to remove interference signals of multiple aggressor transmitters from the Rx signal.
