Cognitive Radio Primary User Detection

详 情 说 明

Cognitive Radio is a technology that allows for the efficient utilization of radio spectrum. It enables devices to detect and utilize unused or underutilized frequency bands, known as white spaces. One of the key challenges in Cognitive Radio is the detection of Primary Users, who are the licensed users of the spectrum. Primary User Detection is the process of identifying whether a frequency band is currently occupied by a Primary User or not. This detection is crucial for Cognitive Radio devices to avoid interference with licensed users and ensure efficient spectrum sharing. Therefore, Primary User Detection plays a vital role in the success and effectiveness of Cognitive Radio systems.
