The Information Theoretic Approach to Signal Anomaly Detection for Cognitive Radio
Figure 12
Performance of the KLD-based anomaly detection scheme under various histogram bin counts. The window size is set at s and the decimation factors used are and . Generally, a larger number of bins lead to poorer performance due to increased noise in the estimates. However, the rate of change is small and therefore the drop in performance is insignificant over a wide range of bin resolutions.
