Integrative Spectrum Sensing in Cognitive Radio Using Wireless Networks

Abstract

The entire operation of cognitive radio completely depends on the spectrum sensing technology in various areas. The main function of cognitive radio is to detect unused or unchecked spectrum and sharing it to other user without causing harmful interference to the primary user induced by reporting phase. Initially it requires different phases such as detection phase and reporting phase. In detection phase cognitive users detects the presence of primary users (Authenticated user). In reporting phase cognitive user forward their detection report to fusion center on existing system. In this, we proposed to analyze the effect of ROC (Receiver Operating Characteristics) with and without dedicated reporting channel in various specifications.
