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 ...

The future of two-way radio communication lies in the ability to use a single device to communicate as a network with other types of devices, maximize the use of limited bandwidth and harness the ...

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 ...

In the future, soldiers on the ground may need to do only one thing for a range of radio operations: turn on the equipment. Once engaged, the so-called cognitive radios would be able to detect other ...

Virginia Tech's Center for Wireless Telecommunications is developing a high-capacity communications system that would be smart enough to configure itself to work through all sorts of interference.

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) ...
