Spiking Neural Belief Propagation Decoder for LDPC Codes with Small Variable Node Degrees
Alexander von Bank, Eike-Manuel Edelmann, Jonathan Mandelbaum +1
Spiking neural networks (SNNs) promise energy-efficient data processing by imitating the event-based behavior of biological neurons. In previous work, we introduced the enlarge-lik…
Spiking Neural Belief Propagation Decoder for Short Block Length LDPC Codes
Alexander von Bank, Eike-Manuel Edelmann, Sisi Miao +2
Spiking neural networks (SNNs) are neural networks that enable energy-efficient signal processing due to their event-based nature. This paper proposes a novel decoding algorithm fo…
List-based Optimization of Proximal Decoding for LDPC Codes
Andreas Tsouchlos, Holger Jäkel, Laurent Schmalen
