Improved cooperative spectrum sensing scheme based on dempster-shafer theory in cognitive radio network

Show other versions (1)

An improved cooperative spectrum sensing scheme based on dempster-shafer evidence theory in cognitive radio networks was proposed.In the local sensing period,the projection approximation algorithm was introduced to reduce bandwidth for cooperation.In the fusion period,credibility was calculated by t...
