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 ...
Link adaptation for MIMO OFDM visible light communication systems
(IEEE-Inst Electrical Electronics Engineers Inc, 2017)
In this paper, we investigate link adaptation for an orthogonal frequency division multiplexing (OFDM)-based multiple-input multiple-output (MIMO) visible light communication (VLC) system. The proposed adaptive OFDM VLC ...
Flexible radio access beyond 5G: A future projection on waveform, numerology, and frame design principles
(IEEE-Inst Electrical Electronics Engineers Inc, 2017)
To address the vast variety of user requirements, applications, and channel conditions, flexibility support is strongly highlighted for 5G radio access technologies (RATs). For this purpose, usage of multiple orthogonal ...
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 ...
Joint time-frequency alignment for PAPR and OOBE suppression of OFDM-based waveforms
(IEEE-Inst Electrical Electronics Engineers Inc, 2017)
Orthogonal frequency division multiplexing (OFDM) waveform has been adopted by many wireless standards due to its numerous advantages. However, OFDM symbols have two critical drawbacks: high out-of-band emission (OOBE) and ...
