Secret communication on the Z-Channel with cooperative receivers
(
IEEE Computer Society
, 2017 , Conference Paper)
The discrete memoryless Z-Channel with a confidential message and a cooperative receiver (DM-ZC-CMCR) is considered. A noiseless one-sided rate-limited cooperation link exists between the two receivers. The secrecy level ...
Carrier Aggregation for Cooperative Cognitive Radio Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
The ever-increasing demand for mobile Internet and high-data-rate applications poses unique challenging requirements for 5G mobile networks, including spectrum limitations and massive connectivity. Cognitive radio and ...
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 ...
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 ...
