Optimal collaborative energy harvesting spectrum sensing with limited time resource
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
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 ...
Throughput of a cooperative energy harvesting secondary user in cognitive radio networks
(
Wiley Blackwell
, 2016 , Article)
This paper investigates the maximum throughput of a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU). The SU is assumed to be an energy harvesting node, which harvests energy packets from the ...
Error probability analysis of energy harvesting relay-Aided cooperative network using hierarchical modulation
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
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 ...
Energy efficient spectrum allocation and mode selection for mission-critical D2D communications
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Device-to-device (D2D) communications is considered as a key enabling technology in future cellular networks and thus, it has become an intriguing topic for research. It refers to an innovative technology that enables User ...
Underlay cognitive radio : What is the impact of carrier aggregation and relaying on throughput ?
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we investigate joint relay selection and optimal power allocation, as a means to maximize the achievable rate of an underlay cooperative cognitive radio with carrier aggregation, taking into account the ...

A Virtual Conference to shed light on the QU's prominent trends and research efforts addressing Corona virus.
Maximum Secondary Stable Throughput of a Cooperative Secondary Transmitter-Receiver Pair: Protocol Design and Stability Analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we investigate the impact of cooperation between a secondary transmitter-receiver pair and a primary transmitter on the maximum stable throughput of the primary-secondary network. Each transmitter, either ...
Secure multiple-users transmission using multi-path directional modulation
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
This work introduces a physical-layer secure multiple-users communication scheme. Our scheme employs the multi-path nature of the wireless channel to provide a different secure communication link for each of the legitimate ...
On the Higher Order Statistics of the Channel Capacity in Dispersed Spectrum Cognitive Radio Systems Over Generalized Fading Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
This work is devoted to the study of dispersed spectrum cognitive radio (CR) systems over independent and nonidentically distributed (i.n.i.d.) generalized fading channels. More specifically, this is performed in terms of ...
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 Paper)
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) ...
