Belief Propagation with Quantum Messages for Symmetric Q-ary Pure-State Channels
Avijit Mandal, Henry D. Pfister
Belief propagation with quantum messages (BPQM) provides a low-complexity alternative to collective measurements for communication over classical--quantum channels. Prior BPQM cons…
A Study of Neural Polar Decoders for Communication
Rom Hirsch, Ziv Aharoni, Henry D. Pfister +1
In this paper, we adapt and analyze Neural Polar Decoders (NPDs) for end-to-end communication systems. While prior work demonstrated the effectiveness of NPDs on synthetic channels…
Neural Polar Decoders for Deletion Channels
Ziv Aharoni, Henry D. Pfister
This paper introduces a neural polar decoder (NPD) for deletion channels with a constant deletion rate. Existing polar decoders for deletion channels exhibit high computational com…
Neural Polar Decoders for DNA Data Storage
Ziv Aharoni, Henry D. Pfister
Synchronization errors, such as insertions and deletions, present a fundamental challenge in DNA-based data storage systems, arising from both synthesis and sequencing noise. These…
Code Rate Optimization via Neural Polar Decoders
Ziv Aharoni, Bashar Huleihel, Henry D Pfister +1
This paper proposes a method to optimize communication code rates via the application of neural polar decoders (NPDs). Employing this approach enables simultaneous optimization of…
From Bit to Block: Decoding on Erasure Channels
Henry D. Pfister, Oscar Sprumont, Gilles Zémor
We provide a general framework for bounding the block error threshold of a linear code over the erasure channel in terms of its bit error threshold. Our…
