Semi-Blind Joint Channel and Symbol Estimation for Beyond Diagonal Reconfigurable Surfaces
Gilderlan Tavares de Araújo, André L. F. de Almeida, Buno Sokal +1
The beyond-diagonal reconfigurable intelligent surface (BD-RIS) is a recent architecture in which scattering elements are interconnected to enhance the degrees of freedom for wave…
Beamforming Saturation in Two-Timescale RIS-assisted Communication
Masoud Sadeghian, Angel Lozano, Gabor Fodor
This paper considers wireless communication assisted by a reconfigurable intelligent surface (RIS), focusing on the two-timescale approach, in which the RIS phase shifts are optimi…
One Target, Many Views: Multi-User Fusion for Collaborative Uplink ISAC
Sajad Daei, Gabor Fodor, Mikael Skoglund
We propose a novel pilot-free multi-user uplink framework for integrated sensing and communication (ISAC) in mm-wave networks, where single-antenna users transmit orthogonal freque…
When Near Becomes Far: From Rayleigh to Optimal Near-Field and Far-Field Boundaries
Sajad Daei, Gabor Fodor, Mikael Skoglund
The transition toward 6G is pushing wireless communication into a regime where the classical plane-wave assumption no longer holds. Millimeter-wave and sub-THz frequencies shrink w…
