Recent Research Progress on Holographic MIMO and Stackable Intelligent Metasurface
Talk of Md. Jahangir Hossain, University of British Columbia Kelowna, Canada
Abstract: While massive MIMO underpins 5G networks with beamforming and spatial multiplexing, 6G demands unprecedented spectral and energy efficiency as well as scalability. To transcend the physical constraints and power consumption of conventional arrays, holographic MIMO (HMIMO) and stacked intelligent metasurfaces (SIM) have emerged as paradigm 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 results will provide key insights into how EE varies with operating conditions and surface dimensions. Second, he will talk about the achievable capacity of HMIMO systems and scenarios where sub-wavelength packing yields capacity improvements over traditional MIMO systems across various propagation environments. Third, he will introduce a wave–digital joint processing framework for channel estimation and precoding in SIM-aided massive MIMO systems. This framework reduces the number of RF chains required, significantly saving costs and improving energy efficiency.
