Unequal Error Protection: An Information-Theoretic Perspective [PDF]
IEEE Transactions on Information Theory, 2009 An information theoretic framework for unequal error protection is developed in terms of the exponential error bounds. The fundamental difference between the bit-wise and message-wise unequal error protection (UEP) is demonstrated, for fixed length block codes on DMCs without feedback. Effect of feedback is investigated via variable length block codes.

Autoencoder-Based Unequal Error Protection Codes [PDF]
IEEE Communications Letters, 2021 We present a novel autoencoder-based approach for designing codes that provide unequal error protection (UEP) capabilities. The proposed design is based on a generalization of an autoencoder loss function that accommodates both message-wise and bit-wise UEP scenarios.

Unequal Error Protection of Memories in LDPC Decoders [PDF]
IEEE Transactions on Computers, 2015 Memories are one of the most critical components of many systems: due to exposure to energetic particles, fabrication defects and aging they are subject to various kinds of permanent and transient errors. In this scenario, Unequal error protection (UEP) techniques have been proposed in the past to encode stored information, allowing to detect and ...

Video prioritization for Unequal Error Protection
2011 IEEE International Conference on Consumer Electronics (ICCE), 2011 We analyze the effect of packet losses in video sequences and propose a lightweight Unequal Error Protection strategy which, by choosing which packet is discarded, reduces strongly the Mean Square Error of the received ...

Unequal Error Protection SCMA Codebooks
IEEE Transactions on Vehicular Technology, 2019 This paper investigates the design of unequal error protection (UEP) codebooks for sparse code multiple access (SCMA) systems. We propose a joint low-density parity check (LDPC) code and SCMA codebook design approach by incorporating cloud partitioning of codewords in the design of SCMA codebooks with different protection levels.

Unequal error protection transmission for federated learning
IET Communications, 2022 Abstract Communication has been recognized as one of the primary challenges of federated learning (FL), but the actual communication algorithm or protocol design is still rarely involved in the existing studies. In the paper, viewing the model exchange in FL as a special kind of traffic, an unequal error protection (UEP) scheme is ...

Unequal Error Protection in Coded Slotted ALOHA [PDF]
IEEE Wireless Communications Letters, 2016 We analyze the performance of coded slotted ALOHA systems for a scenario where users have different error protection requirements and correspondingly can be divided into user classes. The main goal is to design the system so that the requirements for each class are satisfied.

Expanding Window Fountain Codes for Unequal Error Protection [PDF]
2007 Conference Record of the Forty-First Asilomar Conference on Signals, Systems and Computers, 2007 A novel approach to provide unequal error protection (UEP) using rateless codes over erasure channels, named Expanding Window Fountain (EWF) codes, is developed and discussed. EWF codes use a windowing technique rather than a weighted (non-uniform) selection of input symbols to achieve UEP property.

Unequal error protection by modulation with unequal power allocation
IEEE Communications Letters, 2005In digital communication systems for speech, audio or video signals the individual bits of the transmitted parameters u exhibit different bit error sensitivities. Usually channel coding with unequal error protection (UEP) is applied. However, some transmission systems do not include channel coding for several reasons.

Linear unequal error protection codes
IEEE Transactions on Information Theory, 1981The properties of linear codes over GF (q) that provide unequal error protection (UEP) of information digits are discussed. A design is proposed for optimal binary systematic linear UEP codes. Broad classes of iterative and concatenated UEP codes are constructed. Majority decoding algorithms for linear iterative UEP codes are described.
