Enhanced physical layer security by OFDM signal transmission in fractional Fourier domains
(Institute of Electrical and Electronics Engineers, 2015)
The main idea of physical layer security for wireless communications is making the transmitted signal as meaningless for eavesdroppers. It can be achieved by signal processing techniques. In this study, fractional Fourier ...
Cyclic feature concealing cp selection for physical layer security
(Institute of Electrical and Electronics Engineers Inc., 2014)
Cyclic prefix (CP) utilizing techniques such as orthogonal frequency division multiplexing (OFDM) and singlecarrier frequency domain equalization (SC-FDE) offer significant advantages in equalizing the effect of time ...
On signal space diversity: An adaptive interleaver for enhancing physical layer security in frequency selective fading channels
(Elsevier Science Bv, 2017)
Signal space diversity is a powerful technique that increases reliability of detection over fading channels. In this paper, we explore the ability of this technique to provide secure communication. We enhance the security ...
Cyclic feature suppression for physical layer security
(Elsevier Sciences Bv, 2017)
Cyclic prefix (CP) deploying techniques such as orthogonal frequency division multiplexing (OFDM) and single carrier frequency domain equalization (SC-FDE) offer considerable advantages in terms of equalizing time dispersive ...
