On the Ergodic Capacity for SIM-Aided Holographic MIMO Communications

Anastasios Papazafeiropoulos, Ioannis Bartsiokas, Dimitra I. Kaklamani +1

We derive a novel closed-form lower bound on the ergodic capacity of holographic multiple-input multiple-output (HMIMO) systems enhanced by stacked intelligent metasurfaces (SIMs)…
