Performance Evaluation Algorithm of Digital Modulation Signals Recognition
数字调制信号识别性能的评估方法

Because the accurate rate could not be evaluated objectively and overall in recognition of digital modulation,it was proposed that area under receiver operating characteristic(AUC) was used for assessing the LS-SVM classifier and NN classifier's performance. After using the five characteristics parameters, the classification of digital modulation was successfully realized by adopting the LS-SVM classifier and NN classifier. The values of AUC were used for evaluating the merits and demerits of classifiers. The relevant simulation results shown the average performance of the LS-SVM classifier is better than that of the NN classifier.
