Asynchronous cooperative diversity [PDF]
IEEE Transactions on Wireless Communications, 2006 Cooperative diversity, which employs multiple nodes for the simultaneous relaying of a given packet in wireless ad hoc networks, has been shown to be an effective means of improving diversity, and, hence, mitigating the detrimental effects of multipath fading.

Throughput analysis of ALOHA with cooperative diversity [PDF]
IEEE Communications Letters, 2008 Cooperative transmissions emulate multi-antenna systems and can improve the quality of signal reception. In this paper, we propose and analyze a cross layer random access scheme, C-ALOHA, that enables cooperative transmissions in the context of ALOHA ...

A Survey on Cooperative Diversity for Wireless Networks
IEEE Communications Surveys and Tutorials, 2011 Diversity, i.e. transmitting multiple replicas of a signal, may mitigate fading in wireless networks. Among other diversity techniques, the space diversity of multi-antenna systems is particularly interesting since it can complement other forms of diversity.

Distributed Reed-Solomon Coded Cooperative Space-Time Labeling Diversity Network [PDF]
Radioengineering, 2022 This paper proposes a distributed Reed-Solomon coded cooperative labeling diversity (DRSCC-LD) scheme over the Rayleigh frequency-flat fast fading channel to further improve the BER performance. The non-binary Reed-Solomon (RS) code with more consecutive

Cooperative Diversity in a Spectrum Sharing Environment [PDF]
Journal of information and communication convergence engineering, 2011 In this paper, we investigate cooperative diversity in a spectrum sharing environment where secondary users utilize primary users’ spectrum only if the interference power received at the primary users is maintained below a predetermined level. The outage probability of a selective decode-and-forward (DF) based cooperative diversity scheme in the ...
