Jung-Min Park, a researcher at Virginia Tech’s College of Engineering, has received a five-year, $430,000 National Science Foundation (NSF) award to support his efforts to secure cognitive radio technology.

Cognitive radio devices use general purpose processors that run signal handling applications that can change radio frequency, transmission power and other characteristics depending on how the device needs to be used. Cell phones and other conventional wireless devices typically rely on dedicated signal processing hardware. (Rutgers University’s WINLAB is also exploring cognitive radio technologies)
