NOMA Versus Massive MIMO in Rayleigh Fading
Kamil Senel, Hei Victor Cheng, Emil Björnson +1
This paper compares the sum rates and rate regions achieved by power-domain NOMA (non-orthogonal multiple access) and standard massive MIMO (multiple-input multiple-output) techniq…
Human and Machine Type Communications can Coexist in Uplink Massive MIMO Systems
Kamil Senel, Emil Björnson, Erik G. Larsson
Future cellular networks are expected to support new communication paradigms such as machine-type communication (MTC) services along with human-type communication (HTC) services. T…
Centralized and Distributed Power Allocation for Max-Min Fairness in Cell-Free Massive MIMO
Sucharita Chakraborty, Emil Björnson, Luca Sanguinetti
Cell-free Massive MIMO systems consist of a large number of geographically distributed access points (APs) that serve users by coherent joint transmission. Downlink power allocatio…
MRT-based Joint Unicast and Multigroup Multicast Transmission in Massive MIMO Systems
Meysam Sadeghi, Emil Björnson, Erik G. Larsson +2
We study joint unicast and multigroup multicast transmission in single-cell massive multiple-input-multiple-output (MIMO) systems, under maximum ratio transmission. For the unicast…
Review of Transition-Metal Diboride Thin Films
Martin Magnuson, Lars Hultman, Hans Högberg
We review the thin film growth, chemistry, and physical properties of Group 4-6 transition-metal diboride (TMB2) thin films with AlB2-type crystal structure (Strukturbericht design…
Resilient Branching MPC for Multi-Vehicle Traffic Scenarios Using Adversarial Disturbance Sequences
Victor Fors, Björn Olofsson, Erik Frisk
An approach to resilient planning and control of autonomous vehicles in multi-vehicle traffic scenarios is proposed. The proposed method is based on model predictive control (MPC),…
