Abstract

In communication device comprising a plurality of distributed transceivers and one or more corresponding antenna arrays, a first distributed transceiver is configured to receive signals comprising one or more first data streams and a second distributed transceiver is configured to receive signals comprising one or more second data streams. One or more components within a transmit processing chain of the first distributed transceiver and/or one or more components within a transmit processing chain of the second distributed transceiver are adjusted to maximize beamforming gain for the one or more first data streams and/or second data streams. A phase of the one or more first data streams and/or the one or more second data streams may be adjusted by the one or more components within a transmit processing chain of the first distributed transceiver and/or the one or more components within a transmit processing chain of the second distributed transceiver.
