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 ...

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 ...

Presented at ION GNSS+, September 2016. The robustness of a GNSS receiver against interferences can be increased significantly by using an adaptive notch filter, which estimates the instantaneous ...

Three's company: interference patterns for one to four slits (expand for full image) A group of physicists in Austria has directed a beam of large molecules at a series of extremely narrow slits to ...

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 ...

Using signal-to-noise measurements from a single commercial-grade L1 GPS receiver, it is possible to detect interference or jamming that is above the thermal noise floor and below a power that causes ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. While a conventional LMS algorithm can cancel static ghosts, it will not handle dynamic ghosts.

Chaotic communication systems and signal processing represent a cutting‐edge field where the inherent unpredictability of non-linear dynamics is harnessed for robust, efficient data transmission. By ...

For something we rely on so heavily, GPS is pretty rubbish. In the open, it is accurate to within a few metres, but in built-up areas it frequently cannot even locate the correct city block. Now a new ...

Delivering digital terrestrial broadcasting radio waves throughout the country requires the installation of a large number of relay broadcasting stations. STRL has ...

Littleton, MA. octoScope Inc. has introduced iGen, the first compact, easy-to-integrate interference generator capable of generating Wi-Fi traffic and other common types of interference, enabling ...

In my column last month (“Get Ready for ATSC 3.0, But Don’t Ignore 1.0”), I compared ATSC 1.0 and ATSC 3.0 reception. While it is being rolled out, ATSC 3.0 is likely to require similar antennas to ...
