Distributed QC-LDPC Coded Spatial Modulation for Half-Duplex Wireless Communications [PDF]

open access: yesRadioengineering, 2022
The bit error rate (BER) performance of spatial modulation (SM) can be further improved by applying quasi-cyclic low-density parity-check (QC-LDPC) codes recommended in 5G to SM.

Network-coding-based coded cooperation

open access: yesJournal of Communications and Networks, 2010
Coded cooperation is a promising user cooperation scheme. In this paper, we first propose a novel network-coding-based coded cooperation scheme. When a user decodes its partner's information correctly in the first frame, it transmits the combination of the partner's parity bits and its own parity bits through network coding in the second frame. This is

On the Performance of Coded Cooperative Communication with Multiple Energy-Harvesting Relays and Error-Prone Forwarding

open access: yesApplied Sciences, 2023
In this paper, we consider a coded cooperative communication network with multiple energy-harvesting (EH) relays. In order to adequately address the problem of error propagation due to the erroneous decoding at the relays, as in the case of conventional ...

A tutorial on network coded cooperation

open access: yesIEEE Communications Surveys & Tutorials, 2016
Network Coding (NC) can significantly help increase the efficient use of network resources. However, directly applying NC to wireless networks is not an effective design solution. Wireless channels are prone to bit errors due to fading, possibly generating erroneous decisions at the relay nodes while applying NC.

Optimized Design of Distributed Quasi-Cyclic LDPC Coded Spatial Modulation

open access: yesSensors, 2023
We propose a distributed quasi-cyclic low-density parity-check (QC-LDPC) coded spatial modulation (D-QC-LDPCC-SM) scheme with source, relay and destination nodes. At the source and relay, two distinct QC-LDPC codes are used.

Code designs for cooperative communication

open access: yesIEEE Signal Processing Magazine, 2007
The goal of this article is to discuss the implementation of two cooperative protocols - decode-and-forward (DF) and estimate-and-forward (EF). In each case, the starting point is an information theoretic random coding scheme, which motivates a practical code construction.

On coding for cooperative data exchange [PDF]

open access: yesIEEE Information Theory Workshop 2010 (ITW 2010), 2010
We consider the problem of data exchange by a group of closely-located wireless nodes. In this problem each node holds a set of packets and needs to obtain all the packets held by other nodes. Each of the nodes can broadcast the packets in its possession (or a combination thereof) via a noiseless broadcast channel of capacity one packet per channel use.

Generalized Network-Coded Cooperation in OFDMA Communications

open access: yesIEEE Access, 2018
Cooperative communication is a well-established technique to obtain diversity and consequently combat the fading inherent to the wireless channel. In a recent work, network-coded cooperation (NCC) along with graph theory-aided subcarrier allocation was ...

Split-extended LDPC codes for coded cooperation [PDF]

open access: yes2010 International Symposium On Information Theory & Its Applications, 2010
We propose a new code design that aims to distribute an LDPC code over a relay channel. It is based on a split-and-extend approach, which allows the relay to split the set of bits connected to some parity-check of the LDPC code into two or several subsets. Subsequently, the sums of bits within each subset are used in a repeat-accumulate manner in order

Reed-Solomon Coded Cooperative Spatial Modulation Based on Nested Construction for Wireless Communication [PDF]

open access: yesRadioengineering, 2021
This paper proposes the Reed-Solomon coded cooperative spatial modulation (RSCC-SM) scheme based on nested construction of two Reed-Solomon (RS) codes over quasi-static Rayleigh fading channel.
