Wireless communication has traditionally been designed to connect human users. The main
design goal was to maximize the data rate while guaranteeing moderate reliability and …

Grant-free protocols exploiting compressed sensing multi-user detection (MUD) are
appealing for solving the random access problem in massive Internet of Things (IoT) …

This paper focuses on the covariance-based activity detection problem in a multi-cell
massive multiple-input multiple-output (MIMO) system. In this system, active devices transmit …

Solving inverse problems requires knowledge of the forward operator, but accurate models
can be computationally expensive and hence cheaper variants are desired that do not …

The Internet of Things paradigm heavily relies on a network of a massive number of machine-
type devices (MTDs) that monitor changes in various phenomena. Consequently, MTDs are …

The rapid evolution of wireless technology has led to the emergence of new use cases and
the deployment of various types of communication devices across broad geographic areas …
