In some embodiments, a method for mitigating interference in a channel having multiple users includes: receiving a plurality of signals from a plurality of antenna elements, the received signals comprised of one or more interfering signals and a signal of interest (SOI); for each of the one or more interfering signals, beamforming the received signals to enhance the interfering signal, generating an estimate of the interfering signal, and adjusting the estimated interfering signal to undo the effects of beamforming; and subtracting each of the estimated interfering signals from each of the received signals to generate a plurality of interference-mitigated received signals.
