Implicit feedback

Not applicable

Occurs in 802.11n when a transmitter and receiver work together to educate each other about the characteristics of the MIMO channel. The transmitter will make phase adjustments based on the information that is returned from the receiver. When using implicit feedback, the beamformer receives long training symbols transmitted by the beamformee, which allow the MIMO channel between the beamformee and beamformer to be estimated.
