Type-Based Unsourced Multiple Access over Fading Channels with Cell-Free Massive MIMO
Kaan Okumus, Khac-Hoang Ngo, Giuseppe Durisi +1
Type-based unsourced multiple access (TUMA) is a recently proposed framework for type-based estimation in massive uncoordinated access networks. We extend the existing design of TU…

An Achievability Bound for Type-Based Unsourced Multiple Access
Deekshith Pathayappilly Krishnan, Kaan Okumus, Khac-Hoang Ngo +1
We derive an achievability bound to quantify the performance of a type-based unsourced multiple access system -- an information-theoretic model for grant-free multiple access with…
