RS + LDPC-Staircase Codes for the Erasure Channel: Standards, Usage and Performance [PDF]
, 2013 Application-Level Forward Erasure Correction (AL-FEC) codes are a key element of telecommunication systems. They are used to recover from packet losses when retransmission are not feasible and to optimize the large scale distribution of contents. In this

Systematic Luby Transform Codes and their Soft Decoding [PDF]
, 2007 Luby Transform codes (LT) were originally designed for the Binary Erasure Channel (BEC) encountered owing to randomly dropped packets in the statistical multiplexing aided classic wireline-based Internet, where transmitted packets are not affected by the

Coded Cooperation for Multiway Relaying in Wireless Sensor Networks
Sensors, 2015 Wireless sensor networks have been considered as an enabling technology for constructing smart cities. One important feature of wireless sensor networks is that the sensor nodes collaborate in some manner for communications.

Jointly designed quasi-cyclic LDPC-coded cooperation with diversity combining at receiver
International Journal of Distributed Sensor Networks, 2020 This correspondence proposes a jointly-designed quasi-cyclic (QC) low-density parity-check (LDPC)-coded multi-relay cooperation with a destination node realized by multiple receive antennas.

Differentially Encoded LDPC Codes—Part II: General Case and Code Optimization
EURASIP Journal on Wireless Communications and Networking, 2008 This two-part series of papers studies the theory and practice of differentially encoded low-density parity-check (DE-LDPC) codes, especially in the context of noncoherent detection. Part I showed that a special class of DE-LDPC codes, product accumulate

Multilevel structured low-density parity-check codes for AWGN and Rayleigh channels
, 2010 We propose a novel class of protograph low-density parity-check (LDPC) codes having a combinatorial rather than a random structure, which are termed multilevel-structured (MLS) LDPC codes. It is demonstrated that they posses a strikingly simple structure

Jointed LDPC codes design for half-duplex relay channels
Tongxin xuebao, 2013 In order to increase the coding gain of decode-and-forward half-duplex relay channel, a jointed LDPC coding structure and its corresponding optimization scheme was proposed. Novel structure made the subcodes of both source and relay nodes as parts of the
