Modulation Optimization for Achieving Energy Efficient Communications over Fading Channels
(IEEE, 2012)
It is commonly assumed that the energy consumption of wireless communications is minimized when low-order modulations such as BPSK are used. Nevertheless, the literature provides some evidence that low-order modulations ...
ECG Monitoring Using Android Mobile Phone and Bluetooth
(Ieee, 2015-01-01)
This paperwork describes the development and test of circuitry and software to enable the use of Android mobile phones equipped with Bluetooth to receive the incoming electrocardiogram (ECG) signal from a user and show it ...
Wireless-Powered Full-Duplex UAV Relay Networks over FTR Channels
(2021-01-01)
A thorough understanding of fundamental limits of wireless-powered unmanned aerial vehicle (UAV) relay networks in millimeter waves is still missing. We narrow this gap by investigating the outage performance of a UAV-assisted ...
Fabrication and characterization of a directional SPIDA antenna for wireless sensor networks.
(IEEE, 2017)
This paper presents the simulation, fabrication and complete characterization of a 2.4 GHz directional antenna designed for Wireless Sensor Network (WSN) nodes, named SPIDA. The use of this kind of antennas empowers the ...
