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 ...

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 ...

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 ...

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’ ...

The following is excerpted from Chapter 5 of RF & Wireless Technologies by Bruce Fette. If you order a copy of this book before December 31, 2007 you can receive additional 20% off. Visit ...

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 ...

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.

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 ...
