Fusion Rule for Cooperative Spectrum Sensing in Cognitive Radio

摘要: The increasing demands for wireless communication in all fields of life indicate a promising commercial potential. Cognitive radio (CR) is introduced as the that can replace present smart phones future. Cooperative spectrum sensing considered an important step toward coexistence CRs with primary users. Spectrum needs to be reliable at anywhere any time. In this paper, we put forward scenario where cooperative may not due specialty region. We also propose fusion rule make decision those regions. have analyzed performance under Rayleigh fading channel and shadowing. Two separate simulation setups been used model these scenarios. Performance proposed compared other rules literature. feature adjustable weights according position has enabled perform better scenarios considered. With adaptability, work well related sensing.
