Distributed secure transmission for covert communication under multi‐user network
IET Communications, 2022 In order to counter the double attack with wardens and eavesdroppers in the practical scenario, a distributed transmission scheme with security and covertness is proposed, which combines coding techniques and transmission protocol.

2012 IEEE International Symposium on Information Theory Proceedings, 2012 This paper proposes a concept called rateless feedback coding. We redesign the existing LT and Raptor codes, by introducing new degree distributions for the case when a few feedback opportunities are available. We show that incorporating feedback to LT codes can significantly decrease both the coding overhead and the encoding/decoding complexity ...

Proceedings of the 10th ACM Workshop on Hot Topics in Networks, 2011 A fundamental problem in wireless networks is to develop communication protocols that achieve high throughput in the face of noise, interference, and fading, all of which vary with time. An ideal solution is a rateless wireless system, in which the sender encodes data without any explicit estimation or adaptation, implicitly adapting to the level of ...

Weighted zigzag decodable fountain codes for unequal error protection
IET Communications, Volume 16, Issue 17, Page 2082-2090, October 2022., 2022 Abstract By combining bit‐shift and exclusive‐or operations, a weighted zigzag decodable fountain code is proposed to achieve an unequal error protection property. In the proposed scheme, the input symbols of different importance levels are first pre‐coded into variable nodes using low‐density parity‐check codes.

Expanding window fountain codes for unequal error protection [PDF]
, 2009 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.

CRC‐AFC‐based dynamic spectrum resource optimisation for URLLC access in 5G‐advanced and 6G
IET Signal Processing, Volume 16, Issue 8, Page 885-896, October 2022., 2022 Abstract Ultra‐reliable low‐latency communication (URLLC) has the most stringent end‐to‐end communication performance requirements among the three major 5G scenarios. The URLLC enhancement research on 5G‐advanced and 6G needs to be explored continuously.

Capacity-achieving rateless polar codes [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 A rateless coding scheme transmits incrementally more and more coded bits over an unknown channel until all the information bits are decoded reliably by the receiver. We propose a new rateless coding scheme based on polar codes, and we show that this scheme is capacity-achieving, i.e.

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 The future communication requirements for industrial automation will differ significantly from existing technologies. Traffic in Industry 4.0 imposes real‐time requirements, requiring ultra‐reliable communication (URC) with high reliability and minimal latency. The demand for ultra‐high reliability as high as 99.999999 percent and as low as 1 ms end‐to‐

Rateless Distributed Source Code Design [PDF]
Proceedings of the 5th International Mobile Multimedia Communications Conference, 2009 Over the past decade, rateless codes, i.e., digital fountain codes, have emerged as an efficient and robust solution for reliable data transmission over packet erasure networks and a particularly suitable one for multicasting and broadcasting applications where users may experience variable channel conditions and packet loss rates, such as mobile ...
