信道重叠信号分离方法的发展与展望

A Review of Single Channel Separation Algorithms of Overlapped Multi-components

单信道多个时频重叠信号分量的分离，即仅利用一个信道或阵元接收，进行多个时频重叠信号分量的分离，是一个非常具有挑战性的工作，具有非常重要的实际应用和理论研究价值．本文从单信道分量信号定义，到信号分量可分离性分析，再到分离方法，对单信道重叠信号分离这一问题的发展过程和最新研究进展，以及一些领域中的应用进行了系统的介绍，并进一步讨论了其面临的问题和挑战．

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.
