Figure 6From: A belief-based approach to spectrum occupancy mappingResults of Dempster-Shafer analysis for shadowing and sensing inaccuracies. Results of Dempster-Shafer analysis for example including shadowing with standard deviation 10 dB, sensor accuracy and location errors. (a) True power levels (dBm). (b) True boundaries for Pthresh=−60 dBm. (c) Belief that power exceeds Pthresh for (Σ+Φ)=0. (d) Belief that power exceeds Pthresh for (Σ+Φ)=10. (e) Belief that power exceeds Pthresh for (Σ+Φ)=20. (f) Belief that power exceeds Pthresh for (Σ+Φ)=30.Back to article page
