The next wave of wireless technologies is proliferating in connecting things among
themselves as well as to humans. In the era of the Internet of Things (IoT), billions of …

This article introduces a novel scheme, termed coded compressed sensing, for unsourced
multiple-access communication. The proposed divide-and-conquer approach leverages …

Multiple access technology played an important role in wireless communication in the last
decades: it increases the capacity of the channel and allows different users to access the …

This article presents a novel transmission scheme for the unsourced, uncoordinated
Gaussian multiple access problem. The proposed scheme leverages notions from single …

We consider the unsourced random access problem on a Rayleigh block-fading AWGN
channel with multiple receive antennas. Specifically, we treat the slow fading scenario …

Sparse regression codes with approximate message passing (AMP) decoding have gained
much attention in recent times. The concepts underlying this coding scheme extend to …

We put forward a new algorithmic solution to the massive unsourced random access (URA)
problem, by leveraging the rich spatial dimensionality offered by large-scale antenna arrays …

This article is a tutorial introduction to the field of unsourced multiple access (UMAC)
protocols. We first provide a historical survey of the evolution of random access protocols …

Massive machine-type communications (mMTC) is one of the key application scenarios for
future 5G networks. In the literature, this problem is known as unsourced random access. We …

This paper investigates the unsourced random access (URA) scheme to accommodate
numerous machine-type users communicating to a base station equipped with multiple …
