- Definition -> A radio that is aware of its environment and adjusts its behavior accordingly
(What to adjust = frequency, power, modulation based on sensed spectrum)
- Goal -> Increase spectrum utilization without causing interference
- Fixed spectrum management -> New and more efficient management techniques
- "Whitespace"
- Cognitive device
- Opportunistic Spectrum Sharing (OSS) paradigm
- Dynamic Spectrum Access (DSA)
- Software Defined Radio (SDR)
- Spectrum Sensing: Spectrum sensing algorithm
- CR R&D Testbed
