Spectrum Efficiency and Processing Latency Trade-offs in Panel-Based LIS
Lina Tinnerberg, Dumitra Iancu, Ove Edfors +2
The next generation wireless systems will face stringent new requirements, including ultra-low latency, high data rates and enhanced reliability. Large Intelligent Surfaces, is one…
Large Intelligent Surfaces with Low-End Receivers: From Scaling to Antenna and Panel Selection
Ashkan Sheikhi, Juan Vidal Alegría, Ove Edfors
Feasibility of the promising large intelligent surface (LIS) concept, as well as its scalability, relies on the use of low-cost hardware components, raising concerns about the effe…
Over-the-Air DPD and Reciprocity Calibration in Massive MIMO and Beyond
Ashkan Sheikhi, Ove Edfors, Juan Vidal Alegría
Non-linear transceivers and non-reciprocity of downlink and uplink channels are two major challenges in the deployment of massive multiple-input-multiple-output (MIMO) systems. We…
Channel Orthogonalization in Panel-Based LIS
Juan Vidal Alegría, Ove Edfors
Large intelligent surface (LIS) has gained momentum as a potential 6G-enabling technology that expands the benefits of massive multiple-input multiple-output (MIMO). On the other h…
Channel Orthogonalization with Reconfigurable Surfaces: General Models, Theoretical Limits, and Effective Configuration
Juan Vidal Alegría, Johan Thunberg, Ove Edfors
We envision a future in which multi-antenna technology effectively exploits the spatial domain as a set of non-interfering orthogonal resources, allowing for flexible resource allo…
