LDPC Decoding with Degree-Specific Neural Message Weights and RCQ Decoding [PDF]

open access: greenarXiv, 2023
Recently, neural networks have improved MinSum message-passing decoders for low-density parity-check (LDPC) codes by multiplying or adding weights to the messages, where the weights are determined by a neural network. The neural network complexity to determine distinct weights for each edge is high, often limiting the application to relatively short ...

FPGA Implementations of Layered MinSum LDPC Decoders Using RCQ Message Passing [PDF]

open access: greenarXiv, 2021
Non-uniform message quantization techniques such as reconstruction-computation-quantization (RCQ) improve error-correction performance and decrease hardware complexity of low-density parity-check (LDPC) decoders that use a flooding schedule. Layered MinSum RCQ (L-msRCQ) enables message quantization to be utilized for layered decoders and irregular ...

A Reconstruction-Computation-Quantization (RCQ) Approach to Node Operations in LDPC Decoding [PDF]

open access: greenarXiv, 2020
In this paper, we propose a finite-precision decoding method that features the three steps of Reconstruction, Computation, and Quantization (RCQ). Unlike Mutual-Information-Maximization Quantized Belief Propagation (MIM-QBP), RCQ can approximate either belief propagation or Min-Sum decoding.

Reconstruction-Computation-Quantization (RCQ): A Paradigm for Low Bit Width LDPC Decoding [PDF]

open access: greenarXiv, 2021
This paper uses the reconstruction-computation-quantization (RCQ) paradigm to decode low-density parity-check (LDPC) codes. RCQ facilitates dynamic non-uniform quantization to achieve good frame error rate (FER) performance with very low message precision. For message-passing according to a flooding schedule, the RCQ parameters are designed by discrete

Spectral rate theory for projected two-state kinetics [PDF]

open access: yesPhysical Review X 4:011020, 2014, 2012
Classical rate theories often fail in cases where the observable(s) or order parameter(s) used are poor reaction coordinates or the observed signal is deteriorated by noise, such that no clear separation between reactants and products is possible.

On the equivalence between sharing quantum and classical secrets, and error correction [PDF]

open access: yesPhys. Rev. A 88, 042332 (2013), 2012
We present a general scheme for sharing quantum secrets, and an extension to sharing classical secrets, which contain all known quantum secret sharing schemes. In this framework we show the equivalence of existence of both schemes, that is, the existence of a scheme sharing a quantum secret implies the extended classical secret sharing scheme works ...

A Wireless Sensor Network Air Pollution Monitoring System [PDF]

open access: yesInternational Journal of Wireless & Mobile Networks 2.2 (2010) 31-45, 2010
Sensor networks are currently an active research area mainly due to the potential of their applications. In this paper we investigate the use of Wireless Sensor Networks (WSN) for air pollution monitoring in Mauritius. With the fast growing industrial activities on the island, the problem of air pollution is becoming a major concern for the health of ...

Exploring Gap Filling as a Cheaper Alternative to Reading Comprehension Questionnaires when Evaluating Machine Translation for Gisting [PDF]

open access: yesarXiv, 2018
A popular application of machine translation (MT) is gisting: MT is consumed as is to make sense of text in a foreign language. Evaluation of the usefulness of MT for gisting is surprisingly uncommon. The classical method uses reading comprehension questionnaires (RCQ), in which informants are asked to answer professionally-written questions in their ...

What is "Relativistic Canonical Quantization"? [PDF]

open access: yesarXiv, 2005
The purpose of this review is to give the most popular description of the scheme of quantization of relativistic fields that was named relativistic canonical quantization (RCQ). I do not give here the full exact account of this scheme. But with the help of this review any physicist, even not a specialist in the relativistic quantum theory, will be able

Mutual Information-Maximizing Quantized Belief Propagation Decoding of Regular LDPC Codes [PDF]

open access: yesarXiv, 2019
In this paper, we propose a class of finite alphabet iterative decoder (FAID), called mutual information-maximizing quantized belief propagation (MIM-QBP) decoder, for decoding regular low-density parity-check (LDPC) codes. Our decoder follows the reconstruction-calculation-quantization (RCQ) decoding architecture that is widely used in FAIDs.
