In this paper, the authors present a simulation of multipath Rayleigh fading and Recian fading channel. They have used Matlab software for simulation. Simulation was carried out for two different ...

Multipath interference disrupts wireless signals, causing issues like TV ghosting and fading. Now, researchers have developed a passive metasurface that overcomes traditional filtering limits. Using a ...

Critical to the quality of communication between a base-station transmitter and a mobile receiver is the signal's propagation channel. As it is transmitted over the air, the signal is subject to ...

In indoor environments the accuracy of positioning by global navigation satellite systems suffers significantly from signal blockage, reflection and diffraction. To develop advanced receiver position ...

This video presents a study in which researchers developed a passive metasurface that uses a time-varying interlocking mechanism with metal-oxide-semiconductor field-effect transistors to selectively ...
