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)…

ResNet-n/DR: Automated diagnosis of diabetic retinopathy using a residual neural network
Diabetic retinopathy (DR) is a progressive eye disease associated with
diabetes, resulting in blindness or blurred vision. The risk of vision loss was
dramatically decreased with early diagnosis and treatment. Doctors diagnose
DR by examining the…

Improving the detection of intrusion in vehicular ad-hoc networks with modified identity-based cryptosystem
Vehicular ad-hoc networks (VANETs) are wireless-equipped vehicles that
form networks along the road. The security of this network has been a major
challenge. The identity-based cryptosystem (IBC) previously used to secure
the networks suffers from…

Implementation of FinFET technology based low power 4×4 Wallace tree multiplier using hybrid full adder
Many systems, including digital signal processors, finite impulse response
(FIR) filters, application-specific integrated circuits, and microprocessors,
use multipliers. The demand for low power multipliers is gradually rising
day by day in the…

Impact of CuS counter electrode calcination temperature on quantum dot sensitized solar cell performance
In place of the commercial Pt electrode used in quantum sensitized solar
cells, the low-cost CuS cathode is created using electrophoresis. High
resolution scanning electron microscopy and X-ray diffraction were used to
analyze the structure and…

Evaluation of the weighted-overlap add model with massive MIMO in a 5G system
The flaw in 5G orthogonal frequency division multiplexing (OFDM) becomes
apparent in high-speed situations. Because the doppler effect causes frequency
shifts, the orthogonality of OFDM subcarriers is broken, lowering both their
bit error rate…
