Three-Event Energy Detection with Adaptive Threshold for Spectrum Sensing in Cognitive Radio Systems
Publikováno v:
Sensors, Vol 20, Iss 13, p 3614 (2020)
Implementation of dynamic spectrum access (DSA) in cognitive radio (CR) systems requires the unlicensed secondary users (SU) to implement spectrum sensing to monitor the activity of the licensed primary users (PU). Energy detection (ED) is one of the
