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 ...
Optimal power allocation in dispersed cognitive radio systems with carrier aggregation
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we investigate the optimal power allocation problem in dispersed cognitive radios with carrier aggregation. To this end, we model the carrier aggregation using an i - th frequency diversity policy, wherein ...
Eigenvalue-Based Multiple Antenna Spectrum Sensing: Higher Order Moments
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
The problem of multiple antenna spectrum sensing in cognitive radio (CR) networks is studied in this paper. We propose two new invariant constant false-alarm rate eigenvalue-based (EVB) detectors, using the higher order ...
Joint security and energy efficiency in iot networks through clustering and bit flipping
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Channel-aware encryption is investigated as a physical layer security technique in internet of things (IoT) scenarios. Clustering algorithms for grouping sensor nodes into cooperative clusters are proposed, with the purpose ...
Modeling of CubeSat orientation scenario and solar cells for internet of space provision
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
As a cost-effective alternative to traditional satellites, CubeSats have emerged to provide new space experimentation opportunities. The power budgeting of CubeSats is an essential part of the designing process due to the ...
Performance of non-coherent decode-and-forward relaying over time-varying fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Performance analysis of selection combining (SC) for decode-and-forward (DF) relaying in case of general time-varying Rayleigh fading channels is investigated. While auto-regressive (AR) time series model is applied in ...
