DESCRIPTION:Talk of Md. Jahangir Hossain\, University of British Columbia K
 elowna\, Canada\n\nAbstract:  While massive MIMO underpins 5G networks wit
 h beamforming and spatial multiplexing\, 6G demands unprecedented spectral
  and energy efficiency as well as scalability. To transcend the physical c
 onstraints and power consumption of conventional arrays\, holographic MIMO
  (HMIMO) and stacked intelligent metasurfaces (SIM) have emerged as paradi
 gm shifts enabling finegrained electromagnetic (EM) wave control. First\, 
 Dr. Hossain will present closed-form ergodic rates for an HMIMO multi-user
  communication system under an EM-compliant channel model\, which are used
  to maximize the energy efficiency (EE) of such systems. Simulation result
 s will provide key insights into how EE varies with operating conditions a
 nd surface dimensions. Second\, he will talk about the achievable capacity
  of HMIMO systems and scenarios where sub-wavelength packing yields capaci
 ty improvements over traditional MIMO systems across various propagation e
 nvironments. Third\, he will introduce a wave–digital joint processing f
 ramework for channel estimation and precoding in SIM-aided massive MIMO sy
 stems. This framework reduces the number of RF chains required\, significa
 ntly saving costs and improving energy efficiency.\n\nCo-sponsored by: JKU
