From Antenna Abundance to Antenna Intelligence in 6G Gigantic MIMO Systems
Emil Björnson, Amna Irshad, Özlem Tugfe Demir +3
Current cellular systems achieve high spectral efficiency through Massive MIMO, which leverages an abundance of antennas to create favorable propagation conditions for multiuser sp…
Flexible Continuous Aperture Arrays
Kuranage Roche Rayan Ranasinghe, Zhaolin Wang, Giuseppe Thadeu Freitas de Abreu +1
A novel electromagnetic (EM) structure termed flexible continuous aperture array (FCAPA) is proposed, which incorporates inherent surface flexibility into typical continuous apertu…
Low-Complexity Receiver Design for Multicarrier CAPA-based Systems in Doubly-Dispersive Channels
Kuranage Roche Rayan Ranasinghe, Giuseppe Thadeu Freitas de Abreu, Emil Björnson
We propose a novel low-complexity receiver design for multicarrier continuous aperture array (CAPA) systems operating over doubly-dispersive (DD) channels. The receiver leverages a…
Parametrized Stacked Intelligent Metasurfaces for Bistatic Integrated Sensing and Communications
Kuranage Roche Rayan Ranasinghe, Iván Alexander Morales Sandoval, Giuseppe Thadeu Freitas de Abreu +1
We consider stacked intelligent metasurfaces (SIMs) as a tool to improve the performance of bistatic integrated sensing and communications (ISAC) schemes. To that end, we optimize…
