Cross MAC/PHY layer security design using ARQ with MRC and adaptive modulation
(Institute of Electrical and Electronics Engineers Inc., 2016)
In this work, Automatic-Repeat-Request (ARQ) and Maximal Ratio Combination (MRC), have been jointly exploited to enhance the confidentiality of wireless services requested by a legitimate user (Bob) against an eavesdropper ...
A practical physical-layer security method for precoded OSTBC-based systems
(Institute of Electrical and Electronics Engineers, 2016)
In this work, we investigate the security performance obtained by employing a practical precoded orthogonal space time block coding method (POSTBC) in MISO wireless networks. In particular, space time codewords are precoded ...
Secret key generation using channel quantization with SVD for reciprocal MIMO channels
(IEEE, 2016)
The generation of secret keys from reciprocal wireless channel by exploiting their randomness nature, is an emerging area of interest to provide secure communication. One of the main challenges in this domain is to increase ...
Waveform design principles for 5G and beyond
(Institute of Electrical and Electronics Engineers Inc., 2016)
Various emerging applications in future wireless networks require rethinking the access techniques not only from the capacity perspective but also satisfying a wide variety of requirements under the same framework. Traditional ...
Channel independent physical layer security
(Institute of Electrical and Electronics Engineers Inc., 2016)
Security is one of the key requirements of wireless communication systems. By exploiting the broadcast nature of wireless medium, a malicious user might attempt to mislead the legitimate nodes, intercept the communication ...
Static cyclic prefix alignment for OFDM-based waveforms
(Institute of Electrical and Electronics Engineers Inc., 2016)
The cyclic prefix (CP) alignment is an appealing technique for achieving multiple goals such as peak-to-average power ratio (PAPR) reduction, out-of-band (OOB) leakage suppression, and physical layer (PHY) security. It ...
Reliable listen-before-talk mechanism for medical implant communication systems
(Institute of Electrical and Electronics Engineers Inc., 2016)
Health care applications of wireless communication have been finding places dramatically. One of these applications is communication of implantable medical devices (IMD)s. It is expected that the number of IMDs will increase ...
Controlled inter-carrier interference for physical layer security in OFDM systems
(Institute of Electrical and Electronics Engineers Inc., 2016)
Performance of OFDM is known to be very sensitive to frequency synchronization errors. By exploiting this feature, a novel technique is proposed to provide secure communication against eavesdropping. The technique is based ...
On reducing multiband spectrum sensing duration for cognitive radio networks
