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 …

Massive machine-type communications (mMTC) is one of the main three focus areas in the
5th generation (5G) of wireless communications technologies to enable connectivity of a …

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 …

In this paper, we consider a massive grant-free non-orthogonal multiple access (GF-NOMA)
scheme, where devices have strict latency requirements and no retransmission …

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 …

This paper considers sparse device activity detection for cellular machine-type
communications with non-orthogonal signatures using the approximate message passing …

This paper considers a grant-free random access scenario for massive machine-type
communications (mMTC) in which the devices are sporadically active with small payloads …
