Abstract

A system and method for mitigating self-interference in mmWave systems. A transceiver can include a mutual precoder controller that controls both an analog/RF beamforming circuit and a digital/BB beamforming circuit to prefer beams directed along paths in the local RF environment that minimize self-interference. In other cases, a transceiver can include one or more self-interference filters to internally mitigate self-interference.
