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 ...
Energy and spectral efficiency tradeoff in NOMA: Multi-objective evolutionary approaches
(Institute of Electrical and Electronics Engineers Inc., 2020)
Non-orthogonal multiple access (NOMA) deployment in future wireless networks has been recently considered a promising radio access technology to enhance spectral efficiency (SE). However, gain in SE comes always with the ...
Signal relation-based physical layer authentication
(Institute of Electrical and Electronics Engineers Inc., 2020)
Most physical-layer authentication techniques use channel information to prevent spoofing attacks. In such techniques, one must estimate the channel information for each authentication procedure. However, when the number ...
Joint approach to beam optimization and user association
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
Efficiently managed user-cell association is important for self-optimization of communication networks. Edge user performance and fairness of the service quality can be improved by offloading heavily loaded cells to ...
A distributed user-cell association for spectral and energy efficiency tradeoff in massive MIMO UDHNs
(IEEE-Institute of Electrical and Electronics Engineers, 2019)
Massive MIMO enabled ultra-dense heterogeneous networks (UDHNs) have been considered as the indispensable and emerging approach to meet the demand on growing data traffic for next generation networks. Although deployment ...
Secure and reliable IoT communications using nonorthogonal signals' superposition with dual-transmission
(Institute of Electrical and Electronics Engineers Inc., 2020)
Ensuring secure communication for internet of things (IoT) has drawn much attention because of the limitation in the use of conventional cryptographic techniques owing to the unique features of IoT devices such as low ...
On the inherent physical-layer security of receive spatial modulation systems
(Institute of Electrical and Electronics Engineers Inc., 2020)
This paper investigates the physical-layer security attained by Receive Spatial Modulation (RSM) scheme against potential eavesdroppers. The impact of the involved parameters on the bit error rate (BER) at the legitimate ...
