To improve long-range radio frequency communications, researchers at the U.S. Naval Research Laboratory are working on a method of combining signals at the receiver level after multiple relays and a ...

Researchers have developed a new analog photonic correlator that can be used to locate an object transmitting a radio signal. They demonstrated its ability to identify the location of a radio ...

The electrocardiogram (ECG) remains a cornerstone in cardiovascular diagnostics, yet its clinical utility is often compromised by signal distortions introduced during acquisition. Contemporary ...

A new study investigates how “flex power”, a technology that dynamically redistributes satellite signal power to resist interference, affects positioning accuracy and navigation reliability.
