Abstract:
|
Dynamic detection of primary users is one of the main functions
of spectrum sensing for Cognitive Radio (CR) communications
aiming to increase the use of radio spectrum. In
this work the performance of the so-called Candidate power
detector is reported. The main objective of this detector is the
proper spectrum labelling of primary users in cognitive radio
scenarios. The Candidate detector is tuned in order to detect
Digital Video Broadcasting Terrestrial (DVB-T) signals, providing
accurate power level estimates and frequency location
in presence of interference signals or secondary users transmissions.
The advantages of the resulting candidate detector
are shown with respect to the existing alternatives based on
energy detection and cyclo-stationary based detectors. |
