Decoder-in-the-Loop: Genetic Optimization-Based LDPC Code Design [PDF]
IEEE Access, 2019 LDPC code design tools typically rely on asymptotic code behavior and are affected by an unavoidable performance degradation due to model imperfections in the short length regime.

Algebra-Assisted Construction of Quasi-Cyclic LDPC Codes for 5G New Radio
IEEE Access, 2018 Quasi-cyclic LDPC (QC-LDPC) codes have been accepted as the standard codes of 5G enhanced mobile broadband data channel. These standard codes are designed to support multiple lifting sizes and possess rate-compatible property, which can help adapt ...

A High Throughput Implementation of QC-LDPC Codes for 5G NR
IEEE Access, 2019 Quasi-cyclic low-density parity-check (QC-LDPC) codes are the choice for data channels in the fifth generation (5G) new radio (NR). At the transmitter side, code bits from the QC-LDPC encoder are delivered to the rate matcher.

Asymptotically good Quantum and locally testable classical LDPC codes [PDF]
Symposium on the Theory of Computing, 2021 We study classical and quantum LDPC codes of constant rate obtained by the lifted product construction over non-abelian groups. We show that the obtained families of quantum LDPC codes are asymptotically good, which proves the qLDPC conjecture. Moreover,

Good Quantum LDPC Codes with Linear Time Decoders [PDF]
Symposium on the Theory of Computing, 2022 We construct a new explicit family of good quantum low-density parity-check codes which additionally have linear time decoders. Our codes are based on a three-term chain (2m× m)V →δ0 (2m)E →δ1 2F where V (X-checks) are the vertices, E (qubits) are ...
