Abstract :
Multiple-input multiple-output (MIMO) techniques have emerged as a key technology for the next-generation wireless communication systems because these techniques enable very high data rate transmission using a limited frequency band. This paper proposed beamforming and antenna design techniques that improve hardware implementation, and described experimental equipment to actualize a wideband asymmetric MIMO-OFDM system.
