| Abstract: | A C band radio signal classification algorithm is proposed based on the principal component analysis （PCA） and fuzzy C means algorithm （FCM）. The dimensionality of cluster data were reduced by using the principal component analysis and the cluster data were classified by using fuzzy C means approach. The process of feature selection put forward by experts’ experience was improved. The experiment result proves that this method is more effective and the type of signal can be recognized faster. |
