Improved construction of irregular progressive edge-growth Tanner graphs [PDF]

, 2010
The progressive edge-growth algorithm is a well-known procedure to construct regular and irregular low-density parity-check codes. In this paper, we propose a modification of the original algorithm that improves the performance of these codes in the ...

Analysis of reaction and timing attacks against cryptosystems based on sparse parity-check codes

, 2019
In this paper we study reaction and timing attacks against cryptosystems based on sparse parity-check codes, which encompass low-density parity-check (LDPC) codes and moderate-density parity-check (MDPC) codes.

Statistical Mechanics of Broadcast Channels Using Low Density Parity Check Codes [PDF]

, 2002
We investigate the use of Gallager's low-density parity-check (LDPC) codes in a broadcast channel, one of the fundamental models in network information theory.

Ultra-Sparse Non-Binary LDPC Codes for Probabilistic Amplitude Shaping

, 2017
This work shows how non-binary low-density parity-check codes over GF($2^p$) can be combined with probabilistic amplitude shaping (PAS) (B\"ocherer, et al., 2015), which combines forward-error correction with non-uniform signaling for power-efficient ...

Design and Analysis of Time-Invariant SC-LDPC Convolutional Codes With Small Constraint Length

, 2017
In this paper, we deal with time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPC-CCs). Classic design approaches usually start from quasi-cyclic low-density parity-check (QC-LDPC) block codes and exploit suitable ...
