Analyzing Finite-length Protograph-based Spatially Coupled LDPC Codes
, 2014 The peeling decoding for spatially coupled low-density parity-check (SC-LDPC) codes is analyzed for a binary erasure channel. An analytical calculation of the mean evolution of degree-one check nodes of protograph-based SC-LDPC codes is given and an ...

Dynamic Continuous Variable Quantum Key Distribution for Securing a Future Global Quantum Network
Advanced Quantum Technologies, Volume 8, Issue 10, October 2025.The article explores securing a dynamic global quantum network using continuous variable QKD, proposing a unified three‐layer network architecture for integrating existing QKD networks. It evaluates secret key rates across various channels and introduces the link capacity as a metric for determining the optimum path for secret key distribution in a ...

Advanced Quantum Technologies, Volume 8, Issue 9, September 2025.Hardware experiments show a single‐layer Quantum Memory Matrix booster cuts logical error sixfold and, when prepended to a [3,1,3]$[3,1,3]$ repetition code, attains 94 % logical fidelity without extra CX gates. QMM dressing also lowers variational‐training loss by 35 %, offering a measurement‐free, resource‐light route to error suppression on NISQ ...

Error Exponents of LDPC Codes under Low-Complexity Decoding
Entropy, 2021 This paper deals with the specific construction of binary low-density parity-check (LDPC) codes. We derive lower bounds on the error exponents for these codes transmitted over the memoryless binary symmetric channel (BSC) for both the well-known maximum ...

Error Exponents of Low-Density Parity-Check Codes on the Binary Erasure Channel
, 2006 We introduce a thermodynamic (large deviation) formalism for computing error exponents in error-correcting codes. Within this framework, we apply the heuristic cavity method from statistical mechanics to derive the average and typical error exponents of ...

Performance Evaluation of Low Density Parity Check (LDPC) Codes Over Gigabit Ethernet Protocol
Transactions on Networks and Communications, 2016 Error Correcting Low density Parity Check codes enable the communication systems to have a low-power, reliable transmission over noisy channels and can achieve data rates very close to Shannon limit when iteratively decoded. They are used in many digital communication systems such as digital video broadcasting (DVB-S2), MIMO-WLAN (802.11n), WMAN ...

5G‐coded fluid antenna multiple access over block fading channels
Electronics Letters, Volume 61, Issue 1, January/December 2025.This letter investigates the use of 5G New Radio (NR) Modulation Coding Scheme (MCS) for FAMA systems to improve its connectivity over block fading channels. In particular, we propose an iterative decoding receiver with iterative interference covariance estimation, designed explicitly for slow fading channels.
