| Abstract: | Single channel separation of overlapped multicomponents, which involves only one channel or one receiving sensor,is a challenging work. It has great importance for both practical application and theoretic research. From the multicomponent signal definition, the signal component separability to the separating methods, this paper presents a systematic survey and review on the development history, the latest research progress of this research and some successful application appearing in the literature. Future problems and challenges in this area need to be urgently resolved are also discussed in this paper. |
