Enhancing the security performance of ostbc using pre-equalicodization
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this study, we first quantify the secrecy performance achieved by employing precoded orthogonal space time block coding (POSTBC) in order to use it as a benchmark for comparison purposes with a new proposed security ...
A survey: Spoofing attacks in physical layer security
(IEEE Computer Society, 2015)
Increasing demand on wireless communications also increases the issues related to communication security. Among different security solutions, physical layer security have recently been gaining many interests by the ...
An efficient security method based on exploiting channel state information (CSI)
(Institute of Electrical and Electronics Engineers Inc., 2017)
A channel amplitude quantization method that can effectively quantize the channel response using just one single threshold value is proposed in order to extract a random manipulating sequence with good secrecy properties. ...
User association techniques in future heterogeneous networks
(Institute of Electrical and Electronics Engineers Inc., 2017)
The exponential increase in the demand of data rate and scarcity of the available spectrum have evolved to the more advanced network topology which efficiently utilizes the radio spectrum such as Heterogeneous Networks ...
Zero tail filter bank spread OFDM
(Institute of Electrical and Electronics Engineers Inc., 2016)
Waveforms proposed for future communication systems aim at fulfilling the demanding requirements of the next generation of 5G applications. In this paper, an enhancement over Zero Tail Discrete Fourier Transform Spread ...
Game theoretical partially overlapping filtered multi-tones in cognitive heterogeneous networks
(Institute of Electrical and Electronics Engineers Inc., 2014)
Partially overlapping tones have recently been paid attention to by the researchers in cognitive heterogeneous networks (HetNets). In this paper, we introduce partial overlapping in the filtered multi-tones instead of full ...
Enhancing physical-layer security in wireless communications using signal space diversity
(Institute of Electrical and Electronics Engineers Inc., 2016)
In this paper, we enhance the security of OFDM systems in frequency selective fading channels using signal space diversity. In rich multipath environments, spatially separated channels are independent to each other. Hence, ...
Air-Ground Doppler-delay spread spectrum for dense scattering environments
(Institute of Electrical and Electronics Engineers, 2015)
Applications using Air-Ground communications are expected to grow in the future. Low altitude phases of these wireless links are considered sever channels, as they experience huge delay and Doppler spreads, however, they ...
PSK modulation/demodulation and performance evaluation in FM band using USRP
(Institute of Electrical and Electronics Engineers Inc., 2018)
Rapid changes in the wireless systems require reconfigurability. So, an efficient and highly configurable hardware is feasible for such kind of systems. Reconfigurability in fixed hardware systems increases complexity. ...
Nucleotide sequence alignment and compression via shortest unique substring
(Springer Verlag, 2015)
Aligning short reads produced by high throughput sequencing equipments onto a reference genome is the fundamental step of sequence analysis. Since the sequencing machinery generates massive volumes of data, it is becoming ...
