The Information Theoretic Approach to Signal Anomaly Detection for Cognitive Radio

Figure 11

Effect of information threshold (9) on detector and for the ICA algorithm. The cluster length utilised is 3. Histogram bin sizes of 8, 16, and 32 are used for comparison. for each shows a sharp decrease when (i.e., ) is increased above a certain limit. Majority of the anomalous events have an information content less than this and miss detection. and yields the best performance.
