Research of LT Code Based on Key Information Feedback in Deep Space Communication
IEEE Access, 2020 CCSDS LDPC code cannot effectively solve the problems of communication interruptions and high communication error rates in deep space communication. An application scheme of digital fountain code for deep space communication is thoroughly studied in this

Rateless Codes with Progressive Recovery for Layered Multimedia Delivery
, 2012 This paper proposes a novel approach, based on unequal error protection, to enhance rateless codes with progressive recovery for layered multimedia delivery. With a parallel encoding structure, the proposed Progressive Rateless codes (PRC) assign unequal

Rateless resilient network coding against byzantine adversaries [PDF]
2013 Proceedings IEEE INFOCOM, 2013 This paper considers rateless network error correction codes for reliable multicast in the presence of adversarial errors. Most existing network error correction codes are designed for a given network capacity and maximum number of errors known a priori to the encoder and decoder.

Intelligent deep reinforcement learning-based scheduling in relay-based HetNets
EURASIP Journal on Wireless Communications and Networking, 2023 We consider a fundamental file dissemination problem in a two-hop relay-based heterogeneous network consisting of a macro base station, a half-duplex relay station, and multiple users. To minimize the dissemination delay, rateless code is employed at the

Intermediate Performance of Rateless Codes [PDF]
2007 IEEE Information Theory Workshop, 2007 Rateless/fountain codes are designed so that all input symbols can be recovered from a slightly larger number of coded symbols, with high probability using an iterative decoder. In this paper we investigate the number of input symbols that can be recovered by the same decoder, but when the number of coded symbols available is less than the total number

Online fountain code with an improved caching mechanism
IET Communications, Volume 18, Issue 20, Page 1813-1825, December 2024.By catching some selected encoded symbols discarded in the original online fountain codes and giving an optimal degree selection strategy of encoded symbols, the proposed online fountain code improves the receiving rules of the encoded symbols. The proposed online codes outperform the state‐of‐art online fountain codes in terms of overhead factors ...

Dynamic control of Coding in Delay Tolerant Networks [PDF]
, 2009 Delay tolerant Networks (DTNs) leverage the mobility of relay nodes to compensate for lack of permanent connectivity and thus enable communication between nodes that are out of range of each other.
