A receiver includes a plurality of antennas; a plurality of front end circuits producing digital signals in response to signals received on the antennas; a beamforming unit weighting and summing the digital signals to produce a first signal; a first stage including a first plurality of modems producing first bit streams in response to components of the first signal, a first plurality of signal reconstruction units producing first signal replicas in response to the first bit streams, and a first active cancellation unit weighting the first signal replicas and subtracting the weighted first signal replicas from the first signal to produce a second signal; and a second stage including a second plurality of modems producing second bit streams in response to components of the second signal, a second plurality of signal reconstruction units producing second signal replicas in response to the second bit streams, and a second active cancellation unit weighting the second signal replicas and subtracting the weighted second signal replicas from the first signal to produce a third signal. A method implemented by the receiver is also provided.
