Abstract :
A beam-tracking algorithm for downlink transmit beamforming in an FDD CDMA cellular wireless system is investigated. The method takes advantage of the power-controlled system and searches for the beamformer direction corresponding to the minimum transmit power. There is no complex computation needed; thus it simplifies the downlink transmit beamforming system.
