Title: Application of beamforming in wireless local area computer networks
Keywords: wireless computer networks; beamforming; precoding; channel state information
Abstract: The present paper addresses the realization of Multiple Input Multiple Output Beamforming (MIMO Beamforming) systems in 802.11n networks. The system design is based on employing Single Value Decomposition (SVD). Results are presented for both the case with perfect and mean channel state information at the transmitter (CSIT). Variety of different antenna configurations and modulation schemes are investigated. For both perfect and mean CSIT systems it is observed performance improvement greater than 2 dB, reaching 3 dB and more for some particular cases.
