To provide reliable transmissions with flexible rates for satellite communications, this paper
presents a novel method of constructing multi-rate quasi-cyclic low-density parity-check …

Due to the rapid development of quantum computing technology, encryption systems based
on computational complexity are facing serious threats. Based on the fundamental theorem …

Progressive edge-growth (PEG) algorithm was proven to be a simple and effective approach
to design good LDPC codes. However, the low-density parity-check (LDPC) constructed by …

In this paper, we propose a principle for improving the “bit duplication” method for designing
rate-compatible low-density parity-check (LDPC) codes. An experiment was carried out in …

В статье предложен усовершенствованный метод внешнего дублирования бит для
разработки кодов с низкой плотностью проверок на чётность (LDPC кодов) …

In this paper, we propose a “bit duplication” design method for rate-compatible low-density
parity-check codes (LDPC). The main idea of the method is to change the structure of …

The present disclosure relates to a communications field, and discloses a method for
generating a base matrix of an LDPC code, an encoding/decoding method, and a device, to …
