Measuring Frequency Availability For Cognitive Radio Networks By Means Of Adaptive Threshold, Isaac Cushman

GS4 Georgia Southern Student Scholars Symposium

Radio Frequency spectrums designated by the FCC broadcast almost all mediums of communication, in both licensed and unlicensed bands, within the United States. As technology rapidly grows however, the availability of open frequencies will quickly decrease. Our goal is to design and experimentally test a system that allows for secondary users to access frequency bands that are not currently being optimally used by the primary users and also determine the effects of mobility on the ability for a sensor to accurately find frequencies by determining an appropriate power level for communication. We set up experimental scenarios in order to test …
