Impact of Channel Correlation on Subspace-Based Activity Detection in Grant-Free NOMA

Bashar Tahir, Stefan Schwarz, Markus Rupp

In this paper, we consider the problem of activity detection in grant-free code-domain non-orthogonal multiple access (NOMA). We focus on performing activity detection via subspace…

Outage Analysis of Uplink IRS-Assisted NOMA under Elements Splitting

Bashar Tahir, Stefan Schwarz, Markus Rupp

In this paper, we investigate the outage performance of an intelligent reflecting surface (IRS)-assisted non-orthogonal multiple access (NOMA) uplink, in which a group of the surfa…

Degrees of Freedom of Certain Interference Alignment Schemes with Distributed CSIT

Paul de Kerret, Maxime Guillaud, David Gesbert

In this work, we consider the use of interference alignment (IA) in a MIMO interference channel (IC) under the assumption that each transmitter (TX) has access to channel state inf…

Influence of Doppler Bin Width on GPS Acquisition Probabilities

Bernhard C. Geiger, Christian Vogel

Acquisition is a search in two continuous dimensions, where the digital algorithms require a partitioning of the search space into cells. Depending on the partitioning of the Doppl…

Energy Management Policies for Energy-Neutral Source-Channel Coding

Paolo Castiglione, Osvaldo Simeone, Elza Erkip +1

In cyber-physical systems where sensors measure the temporal evolution of a given phenomenon of interest and radio communication takes place over short distances, the energy spent…

Performance of Interference Alignment in Clustered Wireless Ad Hoc Networks

R. Tresch, M. Guillaud

Spatial interference alignment among a finite number of users is proposed as a technique to increase the probability of successful transmission in an interference limited clustered…

On the Achievability of Interference Alignment in the K-User Constant MIMO Interference Channel

Roland Tresch, Maxime Guillaud, Erwin Riegler

Interference alignment in the K-user MIMO interference channel with constant channel coefficients is considered. A novel constructive method for finding the interference alignment…

Asymptotic Capacity Results for Non-Stationary Time-Variant Channels Using Subspace Projections

Thomas Zemen, Stefan M. Moser

In this paper we deal with a single-antenna discrete-time flat-fading channel. The fading process is assumed to be stationary for the duration of a single data block. From block to…
