Abstract

Cognitive radio (CR) is a promising technology available to that seeks the range and efficiency of spectrum dependent services. Its system maps unused spectrum, and arrange secondary user (SU) to operate within unoccupied license spectrum. The implementation of CR system guarantees that there are no interferences to primary user (PU) by prior observing and sensing the existing spectrum environment. Spectrum sensing is the main issue ofCR system to prevent the harmful interference to PU as a license user. However, practically detection performance is often compromised with multipath fading, shadowing and uncertainty noises. In order to minimize the impact of these issues, cooperative spectrum sensing and access is an effective method to improve detection performance.
