Distributed and Scalable Uplink Processing for LIS: Algorithm, Architecture, and Design Trade-offs
Jesus Rodriguez Sanchez, Fredrik Rusek, Ove Edfors +1
The Large Intelligent Surface (LIS) is a promising technology in the areas of wireless communication, remote sensing and positioning. It consists of a continuous radiating surface…
Trade-offs in Decentralized Multi-Antenna Architectures: The WAX Decomposition
Juan Vidal Alegría, Fredrik Rusek, Ove Edfors
Current research on multi-antenna architectures is trending towards increasing the amount of antennas in the base stations (BSs) so as to increase the spectral efficiency. As a res…
Trade-offs In Quasi-Decentralized Massive MIMO
Juan Vidal Alegría, Fredrik Rusek, Jesús Rodríguez Sánchez +1
Typical massive multiple-input multiple-output (MIMO) architectures consider a centralized approach, in which all baseband data received by each antenna has to be sent to a central…
Processing Distribution and Architecture Tradeoff for Large Intelligent Surface Implementation
Jesus Rodriguez Sanchez, Ove Edfors, Fredrik Rusek +1
The Large Intelligent Surface (LIS) concept has emerged recently as a new paradigm for wireless communication, remote sensing and positioning. It consists of a continuous radiating…
