Wavelet-based sensing technique in cognitive radio network
Cognitive radio is a smart radio that can change its transmitter parameter
based on interaction with the environment in which it operates. The demand
for frequency spectrum is growing due to a big data issue as many Internet
of Things (IoT)…

Design, simulation, and analysis of microstrip patch antenna for wireless applications operating at 3.6 GHz
In this study, a microstrip patch antenna that works at 3.6 GHz was built and
tested to see how well it works. In this work, Rogers RT/Duroid 5880 has been
used as the substrate material, with a dielectric permittivity of 2.2 and a thickness
of…

A novel compact dual-band bandstop filter with enhanced rejection bands
In this paper, we present the design of a new wide dual-band bandstop filter
(DBBSF) using nonuniform transmission lines. The method used to design
this filter is to replace conventional uniform transmission lines with
nonuniform lines governed by…

Electroencephalography-based brain-computer interface using neural networks
This study aimed to develop a brain-computer interface that can control an
electric wheelchair using electroencephalography (EEG) signals. First, we used
the Mind Wave Mobile 2 device to capture raw EEG signals from the surface of
the scalp. The…

Deep learning approach to DDoS attack with imbalanced data at the application layer
A distributed denial of service (DDoS) attack is where one or more computers
attack or target a server computer, by flooding internet traffic to the server.
As a result, the server cannot be accessed by legitimate users. A result of this
attack…
