A real-time system combining a simulator and a GNSS propagation model reproduces an authentic multipath environment. The propagation model relies on a 3D-model reconstruction of the urban environment, ...

It has long been appreciated that FM reception is vulnerable to multipath propagation. The effect of an echo for instance a reflection off a building is to create high-order harmonic and ...

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 ...

It was late 1984, some 39 years ago this month, and I was new to the company where I still work today. Right out of the chute, the president of the company handed his new D of E an assignment: Fix our ...

Unforeseen RF transmission impairments, such as cordless phones that use the 2.4GHz band, can cause frustration when deploying wireless LANs. In order to maintain happy users, it’s a good idea 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 ...
