Analysis for rank distribution of BATS codes under time-variant channels
Dianxin kexue, 2022 As a two-step coding technique applied in multi-hop networks with a low complexity, the transmission performance of batched sparse (BATS) code was directly related to the rank distribution of the transfer matrix.Based on the assumption that the packet ...

Strong Secrecy on the Binary Erasure Wiretap Channel Using Large-Girth LDPC Codes
, 2011 For an arbitrary degree distribution pair (DDP), we construct a sequence of low-density parity-check (LDPC) code ensembles with girth growing logarithmically in block-length using Ramanujan graphs.

An Integer Erasure Correction Coding and Its Application for Security Enhancement of Encryption
IEEE AccessThis paper presents a new class of erasure-correcting codes (ECCs) aimed at enhancing cryptographic security of certain encryption schemes. The proposed ECCs employ integer arithmetic to encode and decode data bits and can correct all data bytes, each ...

MDS codes on the erasure-erasure wiretap channel
, 2009 This paper considers the problem of perfectly secure communication on a modified version of Wyner's wiretap channel II where both the main and wiretapper's channels have some erasures. A secret message is to be encoded into $n$ channel symbols and transmitted.

International Journal of Distributed Sensor Networks, 2016 In this article, we study secure multipath routing with energy efficiency for a wireless sensor network in the presence of eavesdroppers. We consider two objectives: (1) the multipath routing scheme for maximising the energy efficiency with security ...

Spatially Coupled LDPC Codes for Decode-and-Forward in Erasure Relay Channel
, 2011 We consider spatially-coupled protograph-based LDPC codes for the three terminal erasure relay channel. It is observed that BP threshold value, the maximal erasure probability of the channel for which decoding error probability converges to zero, of ...

Coded Slotted ALOHA: A Graph-Based Method for Uncoordinated Multiple Access [PDF]
, 2015 In this paper, a random access scheme is introduced which relies on the combination of packet erasure correcting codes and successive interference cancellation (SIC). The scheme is named coded slotted ALOHA.

Error-resilient performance of Dirac video codec over packet-erasure channel [PDF]
, 2007 Video transmission over the wireless or wired network requires error-resilient mechanism since compressed video bitstreams are sensitive to transmission errors because of the use of predictive coding and variable length coding.
