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 ...

Telltale signs of multipath are the fluctuations in the signal-to-noise ratios (SNRs) reported by some GNSS receivers. In this month’s column, the authors look at how an analysis of SNR values can be ...

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 ...

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 ...

The author is senior product design engineer for audio processing for Wheatstone. Thanks to Glynn Walden for his questions in last month’s Radio World Reader’s Forum (Jan. 3 issue) regarding KSDS’ ...

Multipath is real and omnipresent, a detriment when GPS is used for positioning, navigation, and timing. The authors look at a technique to reduce multipath by using a pair of antennas on a moving ...

IT has been reported 1 that long-delay multipath effects were observed when pulsed transmissions on 37 Mc./s. from Gibraltar were received in the United Kingdom during very high frequency ...

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 ...

Interoperable multipath hemispherical map (MHM) using overlap-frequency signals across constellations. The top panel shows the flowchart for modelling and correcting multipath in interoperable MHM.

LONDON--(BUSINESS WIRE)--Spirent Communications plc (LSE:SPT), the world leader in global navigation satellite systems (GNSS) testing solutions, has announced the availability of its innovative ...

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 ...

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 ...
