Weighted cooperative spectrum sensing algorithm based on dempster-shafer evidence theory

A weighted cooperative spectrum sensing algorithm based on D-S evidence theory (DS-WCSS) was proposed.The algorithm took energy detector to perform local spectrum sensing,evaluated the credibility difference of cognit ve users according to the means and variances of test statistic in both hypotheses...
