Estimating the number of sources in white Gaussian noise: Simple eigenvalues based approaches
(
Institution of Engineering and Technology
, 2017 , Article)
Estimating the number of sources is a key task in many array signal processing applications. Conventional algorithms such as Akaike's information criterion (AIC) and minimum description length (MDL) suffer from underestimation ...
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 ...
Novel hybrid physical layer security technique in RFID systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
In this paper, we propose a novel PHY layer security technique in radio frequency identification (RFID) backscatter communications system. In order to protect the RFID tag information confidentiality from the eavesdroppers ...
On correlation-based channel sensing with IQ imbalance
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
This paper addresses the problem of the detection of the presence of a pre-classified (i.e., pulse shape is known) signals with IQ imbalance considering free-space path-loss. We study the effect of IQ distortion on the ...
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 ...
