摘要
Abstract
For the presence of interference signals,a modulation recognition algorithm is proposed based on independent component analysis( ICA) and support vector machine( SVM) . The multiple-antenna-recep-tion and the ICA method are used to extract the independent component from the sample vector. The multi-ple-valued classifier based on two-valued SVM is designed. The proposed algorithm has faster training speed and better recognition performance. The extensive simulation results show that the correct ratio of the recognition algorithm is greater than 0. 9 as SIR≥10 dB and speed less than 12 m/s. The corresponding studies are meaningful for engineering application.关键词
