Transmission in millimeter wave (mmW) band has a big potential to provide orders of higher wireless bandwidth. To combat the high channel loss in high frequency band, beamforming is generally taken to transmit along the direction that provides the maximum transmission gain. This requires the MAC protocol to facilitate the finding of the optimal beamforming direction. Exiting protocol suggests the...
Physical layer techniques have come a long way and can achieve very close to Shannon capacity for point-to-pint links. It is apparent that, to further improve network capacity significantly, we have to resort to concurrent transmissions. Many concurrent transmission techniques (e.g., zero forcing, interference alignment and distributed MIMO) are proposed in which multiple senders jointly encode signals...
