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 ...
Mutual coupling compensation in receiving arrays and its implementation on software defined radios
(Institute of Electrical and Electronics Engineers Inc., 2020)
Mutual coupling is compensated in a four element uniform linear receiving array using software defined radios. Direction of arrival (DoA) is estimated in real-time for the array with spacing d=lambda/4. The decoupling ...
Mutual coupling compensation in receiving antenna arrays
(Institute of Electrical and Electronics Engineers Inc., 2020)
Mutual coupling compensation in uniform linear and circular receiving antenna arrays of thin wire dipoles is presented. It was observed that the mutual impedance is independent of the incident angle and depends solely on ...
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 ...
Experimental validation of a novel RLL code for visible light communication
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Flicker arising in visible light communication (VLC) system is typically mitigated by run-length-limited (RLL) codes. The IEEE 802.15.7 standard proposes RLL codes according to the modulation type and data rate. In this ...
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 ...
Measurement based statistical channel characterization of air-to-ground path loss model at 446MHz for narrow-band signals in low altitude UAVs
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Powered by the advances in microelectronics technologies, unmanned aerial vehicles (UAVs) provide a vast variety of services ranging from surveillance to delivery in both military and civilian domains. It is clear that a ...
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 ...
Orthogonal frequency division multiplexing with subcarrier gap modulation
(Institute of Electrical and Electronics Engineers Inc., 2020)
A new modulation scheme called orthogonal frequency division multiplexing with subcarrier gap modulation (OFDM-SGM) is proposed. The proposed scheme embeds extra information bits by exploiting the gap between the active ...
