Radio communications should travel perfectly through space, right? Well, not exactly, as it turns out. There’s plenty to interfere with radio communications away from the surface of Earth, including ...

Cognitive radio networks (CRNs) represent an innovative paradigm in wireless communications that optimises the usage of the limited radio frequency spectrum. By enabling unlicensed secondary users to ...

Dr. Joseph Mitola, Distinguished Professor and Vice President of The Research Enterprise at Stevens Institute of Technology, received the IEEE TCCN Recognition Award at the IEEE International Dynamic ...

In this paper, the simulation of cognitive radio system to must detect the presence of primary user to avoid interference. Spectrum sensing to detect the spectrum holes (unused bands of the spectrum) ...

A combined single-chip radio and baseband processor, the RTU7010, has demonstrated its ability to operate in an ultra-wideband (UWB) cognitive radio system, according to Realtek Semiconductor Corp.
