Flexible Intelligent Metasurface for Downlink Communications under Statistical CSI
Vaibhav Kumar, Anastasios Papazafeiropoulos, Pandelis Kourtessis +4
Flexible intelligent metasurface (FIM) is a recently developed, groundbreaking hardware technology with promising potential for 6G wireless systems. Unlike conventional rigid anten…
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)…
Ergodic Mutual Information and Outage Probability for SIM-Assisted Holographic MIMO Communications
Anastasios Papazafeiropoulos, Pandelis Kourtessis, Dimitra I. Kaklamani +1
Stacked intelligent metasurface (SIM) is a promising enabler for next-generation high-capacity networks that exhibit better performance compared to its single-layer counterpart by…
Channel Estimation for Stacked Intelligent Metasurfaces in Rician Fading Channels
Anastasios Papazafeiropoulos, Pandelis Kourtessis, Dimitra I. Kaklamani +1
The recent combination of the rising architectures, known as stacked intelligent metasurface (SIM) and holographic multiple-input multiple-output (HMIMO), drives toward breakthroug…
STARS-Enabled Full-Duplex Two-Way mMIMO System Under Spatially-Correlated Channels
Anastasios Papazafeiropoulos, Pandelis Kourtessis, Symeon Chatzinotas +2
\underline{S}imultaneous \underline{t}ransmitting \underline{a}nd \underline{r}eflecting \underline{s}urface (STARS)-assisted systems have emerged to fill this gap by providing $ 3…
