`19.3.12 Beamforming
`19,3.12.1 General
`Beamforming is a technique in which the beamformerutilizes the knowledge of the MIMO
`channelto generate a steering matrix Ox that improves reception in the beamformee.
`
`The beamforming steering matrix that is computed (or updated) from a new channel
`measurementreplaces the existing Ox for the next beamformed data transmission. There are
`several methods of beamforming, differing in the way the beamformer acquires the
`knowledge of the channel matrices Hx and on whether the beamformer generates Ox or the
`beamformeeprovides feedback information for the beamformer to generate Ox.
