Polarization-Adjusted Convolutional (PAC) Codes as a Concatenation of Inner Cyclic and Outer Polar- and Reed-Muller-like Codes [PDF]
arXiv, 2023 Polarization-adjusted convolutional (PAC) codes are a new family of linear block codes that can perform close to the theoretical bounds in the short block-length regime. These codes combine polar coding and convolutional coding. In this study, we show that PAC codes are equivalent to a new class of codes consisting of inner cyclic codes and outer polar-

Reordered static layered schedule for 5G low‐density parity‐check codes
Electronics Letters, Volume 60, Issue 7, April 2024.A static layered schedule for the 5G low‐density parity‐check codes is proposed here. The proposed static layered schedule provides better error performance and faster convergence speed than state‐of‐the‐art. Abstract The error performance of the 5G low‐density parity‐check codes is significantly impacted by the update order of layers.

Some variations of Tanner's construction for short length QC‐LDPC codes
Electronics Letters, Volume 60, Issue 3, February 2024.We propose a variation of Tanner's construction for quasi‐cyclic low‐density parity‐check codes in a way that allows us to use NON‐prime lifting sizes by using some arithmetic sequences instead of geometric sequences. We prove two theorems on the values of this lifting sizes so that the resulting code has girth at least 8.

polarRLCE: A New Code‐Based Cryptosystem Using Polar Codes
Security and Communication Networks, Volume 2019, Issue 1, 2019., 2019 Security challenges brought about by the upcoming 5G era should be taken seriously. Code‐based cryptography leverages difficult problems in coding theory and is one of the main techniques enabling cryptographic primitives in the postquantum scenario. In this work, we propose the first efficient secure scheme based on polar codes (i.e., polarRLCE) which

Derived dynamic scheduling for belief propagation decoding of LDPC codes
Electronics Letters, Volume 60, Issue 4, February 2024.Our article introduces two innovative dynamic scheduling strategies, derived informed variable‐to‐check residual belief propagation and derived variable‐node and variable‐to‐check‐edge residual belief propagation, for low‐density parity‐check (LDPC) codes.

Generalized Concatenation for Quantum Codes [PDF]
Proceedings 2009 IEEE International Symposium on Information
Theory (ISIT 2009), Seoul, Korea, June/July 2009, pp. 953-957, 2009 We show how good quantum error-correcting codes can be constructed using generalized concatenation. The inner codes are quantum codes, the outer codes can be linear or nonlinear classical codes. Many new good codes are found, including both stabilizer codes as well as so-called nonadditive codes.
