Secure Communications Using Directional Modulation
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference)
Limitations on the wireless communication resources (i.e., time and frequency) introduces the need for another domain that can help communication systems to match the increasing demand on high data transfer rates and quality ...
The Secure Degrees of Freedom of the MIMO BC and MIMO MAC with Multiple Unknown Eavesdroppers
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference)
We investigate the secure degrees of freedom (SDoF) of a two-transmitter Gaussian multiple access channel with multiple antennas at the transmitters, a legitimate receiver and an unknown number of eavesdroppers each with ...
Analysis of In-band Full-Duplex OFDM Signals Affected by Phase Noise and I/Q Imbalance
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference)
The idea of the simultaneous transmission and reception of data using the same frequency is a potential candidate to be deployed in the next generation wireless communications standard 5G. The In-Band Full-Duplex (IBFD) ...
Innovative ad-hoc wireless sensor networks to significantly reduce leakages in underground water infrastructures
(
IEEE
, 2010 , Conference)
This paper presents an ICT solution to overcome the problem of water dispersion in water distribution networks. Leakage prevention and breaks identification in water distribution networks are fundamental for an adequate ...
Impact of stochastic RF energy harvesting relay on wireless point-to-point network
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference)
In this paper, we study a general practical stochastic energy harvesting (EH) model where in, an EH relay is able to harvest energy from the radio frequency (RF) radiation in a super capacitor. The different aspects of ...
Capacious spread spectrum watermarking utilizing hadamard matrix
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference)
In this paper, a new watermarking method based on spread spectrum technique, which we call capacious spread spectrum (CSS) is proposed. In this method, unlike the traditional spread spectrum watermarking (TSS), more than ...
Error probability analysis of energy harvesting relay-Aided cooperative network using hierarchical modulation
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference)
In this paper, we investigate the performance of energy harvesting relay-Aided cooperative system wherein, the source node transmits hierarchical signal to the relay and destination nodes. But, since in cooperative networks ...
Optimal collaborative energy harvesting spectrum sensing with limited time resource
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference)
We study a collaborative spectrum sensing (CSS) problem with limited time and energy resources in cognitive radio (CR) network. Time duration of sensing and data transmission, if the spectrum is identified as vacant, are ...
Optimized collaborative spectrum sensing in energy harvesting cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference)
We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time and energy resources in energy harvesting cognitive radio (CR) networks. The frame structures for sensing and ...
On the performance of spectrum sensing based on GLR for full-duplex cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference)
In cognitive radio networks, secondary users (SUs) utilize the unused spectrum slots in the assigned band for the primary users (PUs). Conventional cognitive radio networks operate in half-duplex (HD) mode. Recently, ...
