Energy and spectral efficiency tradeoff in NOMA: Multi-objective evolutionary approaches
(Institute of Electrical and Electronics Engineers Inc., 2020)
Non-orthogonal multiple access (NOMA) deployment in future wireless networks has been recently considered a promising radio access technology to enhance spectral efficiency (SE). However, gain in SE comes always with the ...
Malicious relay node detection with unsupervised learning in amplify-forward cooperative networks
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper presents malicious relay node detection in a cooperative network using unsupervised learning based on the received signal samples over the source to destination (S-D) link at the destination node. We consider ...
