Abstract: This letter proposes to break trapping sets of the low-density parity-check (LDPC) codes used in an LDPC-coded modulation system that employs constant composition distribution matchers ...
Abstract: In this letter, we consider the construction of quasi-cyclic (QC) low-density parity-check (LDPC) codes by jointly optimizing the girth g and the number of g-cycles. We first propose a ...
A specialized Graph Neural Network + Reinforcement Learning (GNN+RL) based decoder for quantum LDPC codes, optimized for lifted and balanced product LDPC codes ...
Our post-selection strategies are expected to be particularly useful for offline resource state generation processes (such as magic state preparation) with QLDPC codes. This work is supported by the ...
