Cognitive radio is an intelligent radio wireless communication technology in order to
increase the spectrum efficiency. In this paper one of the most important cognitive radio task …

Cognitive radio (CR) technology has the potential to detect and share the unutilized
spectrum by enabling dynamic spectrum access. To detect the primary users'(PUs) activity …

The primary objective of Cognitive radio is to distinguish the empty or unused spectrum
bands in the range and use them in giving better wireless communication. The intellectual …

Sažetak Zbog sve većeg korištenja bežičnih komunikacijskih tehnologija koje omogućuju
prijenos podataka velikim brzinama, slobodni dijelovi frekvencijskog spektara su postali vrlo …

Cognitive radio allows spectrum bands which is a limited supply to be used efficiently and
actively. Spectrum sensing which is an important function of cognitive radio detects whether …

In this paper, joint compressed sensing (CS)-based estimation of transmit power,
geographical location and frequency bands of active primary users (PUs) using three …

Cognitive radio technology has shown tremendous potential to reduce spectrum paucity
through its spectrum access mechanism. Effective use of the radio spectrum by the …
