Hardware Distortion Modeling for Panel Selection in Large Intelligent Surfaces
Ashkan Sheikhi, Juan Vidal Alegría, Ove Edfors
Hardware distortion in large intelligent surfaces (LISs) may limit their performance when scaling up such systems. It is of great importance to model the non-ideal effects in their…
Increased Multiplexing Gain with Reconfigurable Surfaces: Simultaneous Channel Orthogonalization and Information Embedding
Juan Vidal Alegria, Joao Vieira, Fredrik Rusek
Reconfigurable surface (RS) has been shown to be an effective solution for improving wireless communication links in general multi-user multiple-input multiple-output (MU-MIMO) set…
Trade-Offs in Decentralized Multi-Antenna Architectures: Sparse Combining Modules for WAX Decomposition
Juan Vidal Alegría, Fredrik Rusek
With the increase in the number of antennas at base stations (BSs), centralized multi-antenna architectures have encountered scalability problems from excessive interconnection ban…
Channel Orthogonalization with Reconfigurable Surfaces
Juan Vidal Alegria, Fredrik Rusek
Orthogonal multi-user multiple-input multiple-output (MU-MIMO) channels allow for optimum performance with simplified precoding/equalization, and they achieve maximum multiplexing…
