NOMA for multinumerology OFDM systems
(Wiley Hindawi, 2018)
Nonorthogonal multiple access (NOMA) is a promising technique which outperforms the traditional multiple access schemes in many aspects. It uses superposition coding (SC) to share the available resources among the users ...
Adaptive OFDM-IM for enhancing physical layer security and spectral efficiency of future wireless networks
(Hindawi Limited, 2018)
In this paper, we propose algorithms for enhancing physical layer security and spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) with Index Modulation (IM) systems. Particularly, different activation ...
Secure spatial multiple access using directional modulation
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)
In this paper, we introduce a secure multiple access scheme, which exploits the multipath structure of the channel to create a multi-user interference environment. The generated interference enables legitimate users to ...
