摘要: Automatic modulation classification (AMC) of unknown communications signals is employed in both commercial and military applications, such as cognitive radio, spectrum surveillance, electronic warfare. Most the AMC methods proposed literature are developed for systems with a single transmit antenna. In this paper, an algorithm multiple-input multiple-output (MIMO) proposed, which based on higher-order cumulants. The use cumulants different orders, well their combinations feature vectors investigated. ideal case priori knowledge channel state information (CSI) considered, along setting practical relevance, where matrix blindly estimated through independent component analysis. performance features evaluated simulations compared that average likelihood ratio test (ALRT).
