On the Achievable Rates of OFDM with Common Phase Error Compensation in Phase Noise Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
This paper considers the problem of analytically assessing the maximum achievable rates (capacity) of orthogonal frequency division multiplexing (OFDM) transmissions when the receiver, for complexity reasons, only accounts ...
A Distributed Approach for Networked Flying Platform Association with Small Cells in 5G+ Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
The densification of small cell base stations in a 5G architecture is a promising approach to enhance the coverage area and facilitate the ever increasing capacity demand of end users. However, the bottleneck is an intelligent ...
Dynamic interference-limited relay sharing in cognitive radio networks by using hierarchical modulation
(
Institution of Engineering and Technology
, 2017 , Article)
Sharing a relay in cognitive radio (CR) networks in order to enhance the secondary user's (SU's) performance in an interference-limited scheme is investigated. It is assumed, by utilising hierarchical modulation, a shared ...
Swinging with the Jet Set: Analysis of Electromagnetic Fields Inside Jet Engines - From Numerical and Experimental Analysis to Statistical Analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Analyzing electromagnetic propagation inside jet engine turbines is a challenging and important research topic due to its potential applications in both civil and military fields. Electromagnetic modeling of such complex ...
On the coexistence of a primary user with an energy harvesting secondary user: A case of cognitive cooperation
(
John Wiley and Sons Ltd
, 2016 , Article)
In this paper, we consider a cognitive scenario where an energy harvesting secondary user shares the spectrum with a primary user. The secondary source helps the primary source in delivering its undelivered packets during ...
A simple angle of arrival estimation system
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
We propose a practical, simple and hardware friendly, yet novel and very efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation based system requires a switched beam antenna array ...
The effect of transmitter's eavesdropper CSI on the secure degrees of freedom of the MIMO MAC
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
We investigate the secure degrees of freedom (SDoF) of the two-transmitter multiple access channel (MAC) with multiple antennas transmitters and multiple antennas legitimate receiver in the vicinity of an eavesdropper that ...
On the secure degrees of freedom of the K user MIMO MAC with statistical CSI
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
We investigate the secure degrees of freedom (SDoF) of the K-user MIMO multiple access channel (MAC) in the vicinity of an eavesdropper which is trying to decode the messages sent by the transmitters. The eavesdropper is ...
Self-interference cancellation using time-domain phase noise estimation in OFDM full-duplex systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
In full-duplex systems, the local oscillator phase noise (PN) problem is one of the bottleneck challenges that may face the self-interference cancellation (SIC) stage especially when orthogonal frequency division multiplexing ...
Optimized Error Probability for Weighted Collaborative Spectrum Sensing in Time-and Energy-Limited Cognitive Radio Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
In this paper, a collaborative energy-harvesting cognitive radio (CR) network is considered such that the transmitter of the secondary user (SU) is allowed to harvest signal energy of the primary user (PU) when the presence ...
