University at Buffalo researchers are developing technology based on cognitive radio, a type of wireless communication that instantly finds and uses the best alternative channels. The researchers say the technology could make wireless communications up to 10 times faster.
"The system we're developing eliminates those inefficiencies, allowing the transfer of as much information as possible while minimizing cross-interference," says University at Buffalo professor Dimitris Pados.
The researchers say they will develop algorithms that optimize how the platform will work, and then they will conduct tests of the technology using small unmanned aerial vehicles.
Cognitive radio promises to immediately detect idle channels throughout the radio spectrum and use them to share information.
The researchers are members of the Signals, Communications, and Networking Research Group, which examines wireless communications and networking, cognitive radios, extreme environment communications, secure communications, data hiding, information theory and coding, adaptive signal processing, compressed sensing, fault-tolerant data representation, multimedia systems, magnetic resonance imaging and image reconstruction, intra-body networks, big data, electromagnetic nanonetworks, network coding, large-scale optimization, and machine learning.
