Planar Quantum Low-Density Parity-Check Codes with Open Boundaries
PRX QuantumAlthough high-threshold and low-overhead quantum low-density parity-check (qLDPC) codes, such as bivariate bicycle (BB) codes, can reduce the physical-qubit cost by an order of magnitude compared to the Kitaev toric code, their torus layout remains ...

A construction of the high-rate regular quasi-cyclic LDPC codes
EURASIP Journal on Wireless Communications and Networking, 2019 In this paper, a scheme to construct the high-rate regular quasi-cyclic low-density parity-check (QC-LDPC) codes is developed based on the finite geometry low-density parity-check (LDPC) codes.

Ldpc Code Construction using Randomly Permutated Copies of Parity Check Matrix [PDF]
مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2018 A construction technique is proposed for low-density parity check (LDPC) codes. It uses a base parity check matrix designed from a ran-dom or constructed construction method as Gallager or Quasi-Cyclic LDPC (QC-LDPC) codes in sequence to get codes with ...

The Effect of Saturation on Belief Propagation Decoding of LDPC Codes
, 2014 We consider the effect of LLR saturation on belief propagation decoding of low-density parity-check codes. Saturation occurs universally in practice and is known to have a significant effect on error floor performance.

JCPP Advances, EarlyView.Abstract Background Few studies have used nationwide registry data from both primary and secondary healthcare services to examine the incidence of attention‐deficit/hyperactivity disorder (ADHD) in children while accounting for early risk factors. We aimed to investigate trends in ADHD diagnoses and associated risk factors.

Reordered static layered schedule for 5G low‐density parity‐check codes
Electronics LettersThe error performance of the 5G low‐density parity‐check codes is significantly impacted by the update order of layers. At present, the row degree (RD) and the number of punctured bits (PBs) are widely used to decide the update order of layers. Here, the

Extended Non-Binary Low-Density Parity-Check Codes over Erasure Channels
, 2011 Based on the extended binary image of non-binary LDPC codes, we propose a method for generating extra redundant bits, such as to decreases the coding rate of a mother code.

The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT A high percentage of women who undergo the transition to postmenopause experience both menopausal symptoms and genitourinary syndrome of menopause (GSM). However, GSM is often underdiagnosed. This research aims to identify risk factors that may influence the number of GSM symptoms and whether they cause distress in Taiwanese women > 45 years ...

Stopping Set Distributions of Some Linear Codes [PDF]
, 2010 Stopping sets and stopping set distribution of an low-density parity-check code are used to determine the performance of this code under iterative decoding over a binary erasure channel (BEC).

On Girth Conditioning for Low-Density Parity-Check Codes [PDF]
IEEE Transactions on Communications, 2011 Low-density parity-check (LDPC) codes are gaining interest for high data rate applications in both terrestrial and spatial communications. They can be designed and studied through a bipartite graph whose characteristics affect the performance. This paper proposes a low-complexity method to improve the performance of LDPC codes by selectively removing ...
