Abstract

A communication device may comprise a plurality of distributed transceivers and one or more corresponding antenna arrays. A processor may configure a first distributed transceiver to receive signals comprising one or more first data streams via one or more first communication links. The processor may configure a second distributed transceiver to receive signals comprising one or more second data streams via one or more second communication links. The processor may determine a channel response matrix associated with communication of the one or more first data streams via the one or more first communication links and/or the one or more second data streams via the one or more second communication links. The processor may optimize one or both of link capacity and/or link reliability of the one or more first communication links and/or the one or more second communication links based on the determined channel response matrix.
