Results of Dempster-Shafer analysis for emulated propagation environment. Results of Dempster-Shafer analysis averaged over 100 random sensor locations, for real propagation example with N=100. (a) True spectrum map. (b) True boundaries. (c) Belief that power exceeds Pthresh, (Σ+Φ)=40. (d) Belief that power exceeds Pthresh, (Σ+Φ)=20.
