A Systematic Approach to Incremental Redundancy over Erasure Channels [PDF]
2018 IEEE International Symposium on Information Theory (ISIT), 2018 As sensing and instrumentation play an increasingly important role in systems controlled over wired and wireless networks, the need to better understand delay-sensitive communication becomes a prime issue. Along these lines, this article studies the operation of data links that employ incremental redundancy as a practical means to protect information ...

A Systematic Approach to Incremental Redundancy With Application to Erasure Channels [PDF]
IEEE Transactions on Communications, 2019 This paper focuses on the design and evaluation of pragmatic schemes for delay-sensitive communication. Specifically, this contribution studies the operation of data links that employ incremental redundancy as a means to shield information bits from the degradation associated with unreliable channels. While this inquiry puts forth a general methodology,

Spatially coupled protograph-based LDPC codes for incremental redundancy [PDF]
2012 7th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2012 We investigate a family of protograph based rate-compatible LDPC convolutional codes. The code family shows improved thresholds close to the Shannon limit compared to their uncoupled versions for the binary erasure channel as well as the AWGN channel. In fact, the gap to Shannon limit is almost uniform for all members of the code family ensuring good ...

Delayed Channel State Information: Incremental redundancy with backtrack retransmission [PDF]
2014 IEEE International Conference on Communications (ICC), 2014 In many practical wireless systems, the Signal-to-Interference-and-Noise Ratio (SINR) that is applicable to a certain transmission, referred to as Channel State Information (CSI), can only be learned after the transmission has taken place and is thereby outdated (delayed). For example, this occurs under intermittent interference. We devise the backward

Windowed Joint Detection and Decoding with IR-HARQ for Asynchronous SCMA Systems
Entropy, 2023 To improve the decoding performance of asynchronous sparse code multiple access (SCMA) systems over additive white Gaussian noise (AWGN) channels, this paper proposes a novel windowed joint detection and decoding algorithm for a rate-compatible (RC ...

Relay Switching Aided Turbo Coded Hybrid-ARQ for Correlated Fading Channel [PDF]
, 2011 Hybrid-Automatic-Repeat-reQuest (HARQ) has become an indispensable technique in reliable communications systems. However, its performance is inevitably affected by the channel’s fading correlation. In this paper, we proposed a novel relay-switching aided

Feedback Communication Systems with Limitations on Incremental Redundancy
CoRR, 2013 This paper explores feedback systems using incremental redundancy (IR) with noiseless transmitter confirmation (NTC). For IR-NTC systems based on {\em finite-length} codes (with blocklength $N$) and decoding attempts only at {\em certain specified decoding times}, this paper presents the asymptotic expansion achieved by random coding, provides rate ...

Updating RDFS ABoxes and TBoxes in SPARQL [PDF]
, 2014 Updates in RDF stores have recently been standardised in the SPARQL 1.1 Update specification. However, computing answers entailed by ontologies in triple stores is usually treated orthogonal to updates. Even the W3C's recent SPARQL 1.1 Update language
