Abstract

See full text

A method includes 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. The method also includes, 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 an equalizer array comprising a predetermined channel model; 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.
