A Spectrum Sensing Method Based on Signal Feature and Clustering Algorithm in Cognitive Wireless Multimedia Sensor Networks
Algorithm 1
Spectrum sensing method based on signal feature and clustering algorithm.
Input: () Train data and test data () | () Calculate the distanced between and , get the minimum value of and reclassify it. | () Calculate the mean of all points in the cluster and use the mean as the centroid | Or select the smallest points of distance from one to all points as centroids. | () Calculate | () If the converges then algorithm will stops, otherwise it return the second step. | () Import the test data | () If then output , otherwise output . |
