Transmitter architecture for the evaluation of beamforming schemes in 802.11n wireless LANs

Abstract

The need for speed and reliability in wireless local area networks is constantly increasing. The IEEE 802.11n standard aims to offer better data rates and performances by combining OFDM and MIMO techniques. Transmit beamforming is one of these techniques and should allow a stronger, more reliable signal for the intended user, while reducing interference towards other users. In this paper, we present the realization of an 802.11n transmitter aimed at comparing different transmit beamforming schemes.
