Modulation options for OFDM-based waveforms: Classification, comparison, and future directions
(IEEE-Inst Electrİcal Electronics Engineers Inc, 2019)
This paper provides a comparative study on the performance of different modulation options for orthogonal frequency division multiplexing (OFDM) in terms of their spectral efficiency, reliability, peak-to-average power ...
On physical-layer concepts and metrics in secure signal transmission
(Elsevier Science Bv, 2017)
Communication secrecy in the wireless systems has unique challenges due to broadcasting nature of the radio waves, as compared to its wire-line counterpart. At the same time, different and independent perceptions of the ...
Joint phy/mac layer security design using arq with mrc and null-space independent papr-aware artificial noise in siso systems
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)
Automatic-repeat-request (ARQ) as a MAC layer mechanism and artificial noise (AN) as a physical layer mechanism along with the help of maximal ratio combining (MRC), are jointly designed to achieve secrecy. Basically, a ...
Secure orthogonal transform division multiplexing (OTDM) waveform for 5G and beyond
(IEEE-Inst Electrical Electronics Engineers Inc, 2017)
In this letter, a secure waveform design for future 5G wireless system is proposed. The developed waveform referred to as secure orthogonal transform division multiplexing (OTDM) waveform, is designed to diagonalize the ...
