Channel coding plays a pivotal role in ensuring reliable communication over wireless
channels. With the growing need for ultra-reliable communication in emerging wireless use …

Unsourced random-access (U-RA) is a type of grant-free random access with a virtually
unlimited number of users, of which only a certain number K a are active on the same time …

The development of 6G networks represents a groundbreaking leap in mobile
communication, targeting the creation of an Intelligent Network of Everything that seamlessly …

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

Consider a (multiple-access) wireless communication system where users are connected to
a unique base station over a shared-spectrum radio links. Each user has a fixed number k of …

We consider the problem of signal estimation in a generalized linear model (GLM). GLMs
include many canonical problems in statistical estimation, such as linear regression, phase …

This article introduces a novel concatenated coding scheme called sparse regression LDPC
(SR-LDPC) codes. An SR-LDPC code consists of an outer non-binary LDPC code and an …

We study the Gaussian multiple access channel with random user activity, in the regime
where the number of users is proportional to the code length. The receiver may know some …

Compressed sensing (CS) theory realizes sparse signal sampling at a sub-Nyquist
frequency to reduce the high computational cost of signal processing systems. As one of the …

This paper studies a generalization of sparse superposition codes (SPARCs) for
communication over the complex additive white Gaussian noise (AWGN) channel. In a …
