To Relay or Not To Relay in Cognitive Radio Sensor Networks
(
IEEE
, 2014 , Article)
A recent investigation on MAC layer in cognitive radio networks proposed the primary packet relaying by the secondary node maintaining an extra queue used for this particular addable functionality. Nevertheless, relaying ...
3D Beamforming with Massive Cylindrical Arrays for Physical Layer Secure Data Transmission
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this letter, a novel approach for physical layer security is implemented using massive cylindrical antenna arrays. A part of the arrays is used for transmitting a signal reliably from source to destination using highly ...
On Channel Selection for Carrier Aggregation Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, the problem of sub-channel selection for carrier aggregation (CA) systems is examined. CA enables the achievement of high data rate links via simultaneous transmissions over multiple component carriers. A ...
Distributed power allocation for multi-flow carrier aggregation in heterogeneous cognitive cellular networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, we study distributed power allocation for multiflow carrier aggregation in cognitive cellular networks. Our approach differs from the conventional water filling (WF) algorithm since we deal with heterogeneous ...
Patch antenna array designs for wireless communication applications inside jet engines
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this paper, two different patch antenna geometries are proposed for wireless sensor applications involving electromagnetic propagation from inside the jet engine to our designed relaying antenna at the rim of the inlet. ...
Energy Detection Spectrum Sensing in Full-Duplex Cognitive Radio: The Practical Case of Rician RSI
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
The increased interest in full-duplex communication combined with spectrum utilization enhancements stemming from cognitive radio motivate research activities in full-duplex cognitive radio. Energy detection is among the ...
Thresholds optimization for one-bit feedback multi-user scheduling
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
We propose a new one-bit feedback scheme with scheduling decision based on the maximum expected weighted rate. We show the concavity of the 2-user case and provide the optimal solution which achieves the maximum weighted ...
Residual self-interference analysis for full-duplex OFDM transceivers under phase noise and I/Q imbalance
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
In this letter, we investigate the detrimental effects of phase noise (PN) and in-phase/quadrature (I/Q) imbalance (IQI) on full-duplex OFDM transceivers. In particular, we derive a closed-form expression for the average ...
Centralized and Distributed Cognitive Relay-Selection Schemes for SWIPT Cognitive Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
We investigate the model of a single primary-transceiver pair with multiple secondary-transceiver pairs. The secondary pairs can act as relays for the primary transmitter enabling access to its channel resources. Each ...
Design Challenges of Multi-UAV Systems in Cyber-Physical Applications: A Comprehensive Survey and Future Directions
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Unmanned aerial vehicles (UAVs) have recently rapidly grown to facilitate a wide range of innovative applications that can fundamentally change the way cyber-physical systems (CPSs) are designed. CPSs are a modern generation ...
