In the fifth generation (5G) of wireless communication systems, hitherto unprecedented
requirements are expected to be satisfied. As one of the promising techniques of addressing …

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 …

Compressive Sensing (CS) is a new sensing modality, which compresses the signal being
acquired at the time of sensing. Signals can have sparse or compressible representation …

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

Non-orthogonal multiple access (NOMA) can support more users than OMA techniques
using the same wireless resources, which is expected to support massive connectivity for …

Non-orthogonal multiple access (NOMA) has been regarded as one of the promising key
technologies for future 5G systems. In the uplink grant-free NOMA schemes, dynamic …

Non-orthogonal multiple access (NOMA) is an emerging research topic in the future fifth
generation wireless communication networks, which is expected to support massive …

This letter focuses on joint user activity and data detection in the uplink grant-free non-
orthogonal multiple access systems based on approximate message passing (AMP) and …

Grant-free non-orthogonal multiple access has recently gained significant attention for
reducing signaling overhead in machine-type communications. In this context, compressed …

Given the requirements of increased data rate and massive connectivity in the Internet-of-
things (IoT) applications of the fifth-generation communication systems (5G), non-orthogonal …
