Patent ID: 8577302

Claim:
A system for improving communication, wherein the system comprises: a transmitter configured to send a first plurality of sounding packets and a second plurality of sounding packets; and a receiver configured to receive the first plurality of sounding packets, receive the second plurality of sounding packets, generate a first beamforming estimate based on the first plurality of sounding packets, generate a second beamforming estimate based on the second plurality of sounding packets, and generate a feedback signal based on the difference between the first beamforming estimate and the second beamforming estimate; wherein the receiver directs beamforming according to the feedback signal; and wherein the feedback signal includes only a single bit when the first beamforming estimate and the second beamforming estimate are substantially the same; wherein the feedback signal includes multiple bits when the first beamforming estimate and the second beamforming estimate differ.
