Transmit and receive cooperative cognition: Protocol design and stability analysis
(
IEEE Computer Society
, 2013 , Conference Paper)
In this paper, we investigate the stability of a cooperative cognitive system. We propose a cooperative secondary transmitter-receiver system (CSTR), where, the secondary transmitter (ST) and the secondary receiver (SR) ...
On the Design of a Relay-Assisted Network
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
A relay network composed of a source, a set of relays, and a destination is considered. A queueing framework is proposed, in which each node maintains a buffer to store its incoming traffic. An optimization-based formulation ...
Spectrum-aggregating cognitive multi-antenna user with multiple primary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
We investigate a cognitive radio scenario involving a single cognitive transmitter equipped with K antennas sharing the spectrum with M primary users (PUs) transmitting over orthogonal bands. Each terminal has a queue to ...
ViDMASK dataset for face mask detection with social distance measurement
(
Elsevier B.V.
, 2022 , Article)
The COVID-19 outbreak has extenuated the need for a monitoring system that can monitor face mask adherence and social distancing with the use of AI. With the existing video surveillance systems as base, a deep learning ...
The Role of 5G/6G Networks in Building Sustainable and Energy-Efficient Smart Cities
(
Institute of Electrical and Electronics Engineers Inc.
, 2022 , Conference Paper)
Future wireless networks aim to provide high-energy efficiency, high spectral efficiency, low cost, and support a massive number of connected devices in prospect the evolution of Internet of Things (IoT) and smart cities. ...
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 ...
Time-frequency compressed spectrum sensing in cognitive radios
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
In this paper, we investigate the use of time-frequency analysis for improvement of spectrum sensing in cognitive radios and exploit compressed sensing (sampling) to reduce the extremely high sampling rate of signal in ...
Order Statistics-Based Design of UWB Receivers
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
We propose a non-coherent ultra-wideband (UWB) receiver that leverages a single-sample-per-pulse threshold approach to detect the transmitted symbol and is capable of mitigating the impact of impulse noise. Unlike classical ...
SFET-based multiple antenna spectrum sensing using the second order moments of eigenvalues
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose a new detector for multiantenna spectrum sensing in cognitive radios (CR) by exploiting the Separating Function Estimation Test (SFET) framework. Specifically, we consider a blind scenario for ...
Secure Spatial Multiple Access Using Directional Modulation
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
In this paper, we introduce a secure multiple access scheme, which exploits the multipath structure of the channel to create a multi-user interference environment. The generated interference enables legitimate users to ...
