The Information Theoretic Approach to Signal Anomaly Detection for Cognitive Radio
Figure 10
Performance of the KLD-based anomaly detection scheme under various window lengths and hence the input sample size . Decimation factors (DF) of and are utilised and the number of histogram bins is . In all cases, an increase in the amount of data leads to a better performance. However, beyond a certain window length, the performance is no longer strongly affected.
