A Hybrid Approach to Coded Compressed Sensing Where Coupling Takes Place Via the Outer Code

ICASSP 2021accepted

This article seeks to advance coded compressed sensing (CCS) as a practical scheme for unsourced random access. The CCS algorithm features a concatenated structure where an inner code is tasked with support recovery and an outer code conducts message disambiguation. Recently, the CCS scheme was impr…

An Enhanced Decoding Algorithm for Coded Compressed Sensing

ICASSP 2020accepted

Coded compressed sensing is an algorithmic framework tailored to sparse recovery in very large dimensional spaces. This framework is originally envisioned for the unsourced multiple access channel, a wireless paradigm attuned to machine-type communications. Coded compressed sensing uses a divide-and…

Asynchronous Neighbor Discovery Using Coupled Compressive Sensing

ICASSP 2019accepted

The neighbor discovery paradigm finds wide application in Internet of Things networks, where the number of active devices is orders of magnitude smaller than the total device population. Designing low-complexity schemes for asynchronous neighbor discovery has recently gained significant attention fr…

A Coupled Compressive Sensing Scheme for Unsourced Multiple Access

ICASSP 2018accepted

This article introduces a novel paradigm for the unsourced multiple-access communication problem. This divide-and-conquer approach leverages recent advances in compressive sensing and forward error correction to produce a computationally efficient algorithm. Within the proposed framework, every acti…
