Claim 0:
1. A method comprising:
transmitting, by a transceiver configured to concurrently transmit over multiple transmit paths and receive over multiple receive paths, one or more signals, the transceiver comprising multiple transmit antennas and multiple receive antennas;
determining an equalizer array comprising a predetermined channel model;
for at least one of the multiple receive antennas:
receiving one or more feedback signals from one or more power amplifiers associated with the one or more transmitted signals;
calculating one or more estimated self-interference (SI) signals based on the one or more feedback signals using the equalizer array; and
subtracting the one or more estimated SI signals from one or more receive signals received at the at least one receive antenna to obtain one or more residual signals,

wherein the equalizer array is determined by broadcasting second transmit signals on all of the multiple transmit antennas, and receiving (i) second feedback signals associated with the second transmit signals and (ii) second receive signals received by the multiple receive antennas.
