Error-Correction Performance of Regular Ring-Linear LDPC Codes over Lee Channels
Jessica Bariffi, Hannes Bartz, Gianluigi Liva +1
Most low-density parity-check (LDPC) code constructions are considered over finite fields. In this work, we focus on regular LDPC codes over integer residue rings and analyze their…
Soft-Information Post-Processing for Chase-Pyndiah Decoding Based on Generalized Mutual Information
Andreas Straßhofer, Diego Lentner, Gianluigi Liva +1
Chase-Pyndiah decoding is widely used for decoding product codes. However, this method is suboptimal and requires scaling the soft information exchanged during the iterative proces…
Learning-Based Rich Feedback HARQ for Energy-Efficient Uplink Short Packet Transmission
Martin Voigt Vejling, Federico Chiariotti, Anders Ellersgaard Kalør +3
The trade-off between reliability, latency, and energy efficiency is a central problem in communication systems. Advanced hybrid automated repeat request (HARQ) techniques reduce r…
Rate-Adaptive Protograph MacKay-Neal Codes
Ayman Zahr, Balazs Matuz, Gianluigi Liva
A class of rate-adaptive protograph MacKay-Neal (MN) codes is introduced and analyzed. The code construction employs an outer distribution matcher (DM) to adapt the rate of the sch…
Remote Monitoring of Two-State Markov Sources via Random Access Channels: an Information Freshness vs. State Estimation Entropy Perspective
Giuseppe Cocco, Andrea Munari, Gianluigi Liva
We study a system in which two-state Markov sources send status updates to a common receiver over a slotted ALOHA random access channel. We characterize the performance of the syst…
The Dynamic Behavior of Frameless ALOHA: Drift Analysis, Throughput, and Age of Information
Andrea Munari, Francisco Lazaro, Giuseppe Durisi +1
We study the dynamic behavior of frameless ALOHA, both in terms of throughput and age of information (AoI). In particular, differently from previous studies, our analysis accounts…
