Various embodiments are disclosed for implementing joint non-linear interference cancellation (NLIC) in communication receivers with multiple receiver antennas to cancel or mitigate self-jamming interference from the same aggressor transmitter. A victim receiver may exploit the correlated nature of the interference signals received by the multiple receiver antennas to reduce the computational complexity of an NLIC scheme and improve performance. The victim receiver may select an Rx antenna/Rx chain that experiences the strongest interference from the aggressor transmitter and may perform a full NLIC operation using Tx data from the aggressor transmitter to estimate the strongest interference signal. The NLIC operation may estimate each remaining interference signal by applying a complex coefficient from a single-tap adaptive filter to the estimate of the strongest interference signal. The victim receiver may remove the estimated interference signals from the Rx signals of the respective Rx chains to cancel or mitigate the interference.
