RIS-Assisted Massive MIMO with Multi-Specular Spatially Correlated Fading
Özlem Tuğfe Demir, Emil Björnson
Reconfigurable intelligent surfaces (RISs) have attracted great attention as a potential beyond 5G technology. These surfaces consist of many passive elements of metamaterials whos…
Foundations of User-Centric Cell-Free Massive MIMO
Özlem Tuğfe Demir, Emil Björnson, Luca Sanguinetti
Imagine a coverage area where each mobile device is communicating with a preferred set of wireless access points (among many) that are selected based on its needs and cooperate to…
Cell-Free Massive MIMO with Large-Scale Fading Decoding and Dynamic Cooperation Clustering
Özlem Tuğfe Demir, Emil Björnson, Luca Sanguinetti
This paper considers the uplink of user-centric cell-free massive MIMO (multiple-input multiple-output) systems. We utilize the user-centric dynamic cooperation clustering (DCC) fr…
