Directional modulation (DM) has emerged as a highly promising physical layer security technique that embeds confidential information into the spatial characteristics of the transmitted signal. By ...

Have you ever heard terms like modulation scheme, orthoganal frequency division multiplexing (OFDM), or symbol rate and scratched your head? As new wireless standards emerge, we get excited about the ...

Magnacom emerged from stealth mode claiming it has a new twist on digital modulation technology that provides big gains for any wired or wireless network. The company will license its technology on ...

Wireless communication systems enable the transmission of information without physical conductors by converting digital data into electromagnetic waves and propagating them through air or space. At ...

In the ever-evolving landscape of wireless communication, security remains a paramount concern. A recent study published in Engineering delves into the realm of intelligent covert communication, ...

Researchers have shown that solar cells can be used to achieve underwater wireless optical communication with high data rates. The new approach -- which used an array of series-connected solar cells ...
