On the Reliability Function of Variable-Rate Slepian-Wolf Coding
Entropy, 2017 The reliability function of variable-rate Slepian-Wolf coding is linked to the reliability function of channel coding with constant composition codes, through which computable lower and upper bounds are derived.

Density Evolution for the Design of Non-Binary Low Density Parity Check Codes for Slepian-Wolf Coding [PDF]
IEEE Transactions on Communications, 2014 International audienceIn this paper, we investigate the problem of designing good non-binary LDPC codes for Slepian-Wolf coding. The design method is based on Density Evolution which gives the asymptotic error probability of the decoder for given code ...

Distributed Arithmetic Coding for the Slepian–Wolf Problem [PDF]
IEEE Transactions on Signal Processing, 2009 Distributed source coding schemes are typically based on the use of channels codes as source codes. In this paper we propose a new paradigm, named ldquodistributed arithmetic coding,rdquo which extends arithmetic codes to the distributed case employing sequential decoding aided by the side information.

Symbol positions‐based Slepian–Wolf coding with application to distributed video coding
IET Image Processing, 2020 In this study, the authors will show that coding the positions of the symbols, instead of their values, can be a good way to implement efficient Slepian–Wolf (SW) coding and can reduce the complexity of both the encoder and the decoder.

LDPC code design for asynchronous Slepian-Wolf coding [PDF]
IEEE Transactions on Communications, 2010 We consider asynchronous Slepian-Wolf coding where the two encoders may not have completely accurate timing information to synchronize their individual block code boundaries, and propose LDPC code design in this scenario. A new information-theoretic coding scheme based on source splitting is provided, which can achieve the entire asynchronous Slepian ...

Ensuring data integrity of healthcare information in the era of digital health. [PDF]
Healthc Technol Lett, 2021 Abstract Data integrity continues to be a persistent problem in the current healthcare sector. It ensures that the data is correct and has not even in any manner been improperly changed. Incorrect data might become significant health threats for patients and a big responsibility for clinicians, resulting in problems such as scam, misconduct, inadequate

Human cortical high-gamma power scales with movement rate in healthy participants and stroke survivors. [PDF]
J PhysiolAbstract figure legend Magnetoencephalography data from stroke survivors, healthy, age‐matched control participants and healthy young participants were measured during the execution of a thumb movement task. Movement‐related high‐gamma power was evident in all three groups with a maximum over motor cortical areas contralateral to the performed movement.

LDPCA Code Construction for Slepian-Wolf Coding [PDF]
IEEE Communications Letters, 2011 Error correcting codes used for Distributed Source Coding (DSC) generally assume a random distribution of errors. However, in certain DSC applications, prediction of the error distribution is possible and thus this assumption fails, resulting in a sub-optimal performance. This letter considers the construction of rate-adaptive Low-Density Parity-Check (
