Abstract: While massive MIMO underpins 5G networks with beamforming and spatial multiplexing gains, 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 metasurface (SIM) emerge as paradigm shifts enabling fine-grained electromagnetic (EM) wave control. In Part I of this presentation, 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. The presented simulation results will provide insights into how EE varies with operating conditions and surface dimensions. In Part II, he will discuss a wave–digital joint processing framework for channel estimation and precoding in SIM-aided massive MIMO systems. This framework can reduce the number of RF chains required for MIMO systems, thereby saving costs and improving energy efficiency. Biography: Md.
