Real-Time Text Transmission via LLM-Based Entropy Coding over Fixed-Rate Channels
Vishnu Teja Kunde, Jean-Francois Chamberland, Krishna R. Narayanan +1
Learning, prediction, and compression are intimately connected: a model that accurately predicts the next symbol in a sequence can be coupled with a source coder to compress that s…
Density Evolution Analysis of Sparse-Block IDMA
Jean-Francois Chamberland, Gianluigi Liva, Krishna Narayanan
Sparse block interleaver division multiple access (SB-IDMA) is a recently introduced unsourced multiple access protocol that aims to improve the performance of the grant-free two-s…
Multi-User SR-LDPC Codes
Jamison R. Ebert, Jean-Francois Chamberland, Krishna R. Narayanan
This article introduces a novel non-orthogonal multiple access (NOMA) scheme for coordinated uplink channels. The scheme builds on the recently proposed sparse-regression low-densi…
Evolution of the 5G New Radio Two-Step Random Access towards 6G Unsourced MAC
Patrick Agostini, Jean-Francois Chamberland, Federico Clazzer +7
This report summarizes some considerations on possible evolutions of grant-free random access in the next generation of the 3GPP wireless cellular standard. The analysis is carried…
