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

Applied 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 ...

Network-coding-based coded cooperation
Journal 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

Optimized Design of Distributed Quasi-Cyclic LDPC Coded Spatial Modulation
Sensors, 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.

Network coded modulation for two-way relaying [PDF]
, 2011 Network coding compresses multiple traffic flows with the aid low-complexity algebraic operations, hence holds the potential of significantly improving both the power and bandwidth efficiency of wireless networks.

Outage analysis of superposition modulation aided network coded cooperation in the presence of network coding noise [PDF]
, 2015 We consider a network, where multiple sourcedestination pairs communicate with the aid of a half-duplex relay node (RN), which adopts decode-forward (DF) relaying and superposition-modulation (SPM) for combining the signals transmitted by the source ...

Generalized Network-Coded Cooperation in OFDMA Communications
IEEE 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 ...

Code designs for cooperative communication
IEEE 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]
IEEE 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.

Joint source and turbo trellis coded hierarchical modulation for context-aware medical image transmission [PDF]
, 2013 An iterative Joint Source and Turbo Trellis Coded Hierarchical Modulation is introduced for robust context-aware medical image transmission. Lossless source compression as well as Quality of Service (QoS) might be considered as the main constraints in ...
