Method and apparatus for dynamically selecting the best antennas/mode ports for transmission and reception

摘要: A method and apparatus for dynamically selecting antennas transmission and/or reception. The may be an antenna system, a base station, wireless transmit/receive unit (WTRU), integrated circuit (IC). subset of plurality available use is determined at any given moment in time. comprised by Shelton-Butler matrix fed circular array including selectable mode ports. One or more characteristics, (e.g., cross-correlation, multipath), signals received via the antennas/ ports are analyzed on continual basis, number antennas/mode needed reception determined. At least one associated with signal having better characteristic than other selected. selected antenna/mode port then used
