基于AP聚类的数字信号调制体制识别方法
A Modulation Recognition Method Based on AP
摘要
Abstract
In this investigation,we propose a promising inter-class recognition method based on short time Fourier transform (STFT)and affinity propagation clustering (AP)to solve the problem of recognition among MASK,MFSK and MPSK modulated sig-nal. The inter-class recognition method proposed consists of two parts. Firstly,based on signature analysis of these three types of signal in both time and frequency domain,we extract the time-frequency feature,and secondly,we cluster the signal by affinity propagation clustering technology. This method could find the clustering center and amount automatically and quickly by updating the information iteratively. Experimental simulations verify the superior performance of our presented inter-class recognition scheme even in low-SNR region.关键词
