Root high-order cumulant MUSIC

Digital Signal Processing, 2022
Abstract The ( p , q )th order circularity and non-circularity of non-Gaussian signals are developed for the first time in this paper. The polynomial rooting implementation of the high-order cumulant based multiple signal classification (MUSIC) methods are then investigated, concentrating on the direction-of-arrival estimation of the ( p ...

Clustering Rooted Ordered Trees

2007 IEEE Symposium on Computational Intelligence and Data Mining, 2007
Tree structures have gained popularity for storing data from different domains such as XML documents, bio informatics and so on. Clustering these data can facilitate different operations. In this paper, we propose TreeCluster, a novel and heuristic algorithm for clustering tree structured data.

Robust mixed-order root-music

Circuits Systems and Signal Processing, 2000
In direction finding MUSIC (multiple signal classification) is used in different versions. In certain situations second-order algorithms perform well, whereas in other cases higher-order methods should be preferred. That's why the authors propose the combination of these methods to obtain optimal performance in the case of unknown signal properties. In

On the convergence and roots of order-statistics filters

IEEE Transactions on Signal Processing, 1995
We propose a comprehensive theory of the convergence and characterization of roots of order-statistics filters. Conditions for the convergence of iterations of order-statistics filters are proposed. Criteria for the morphological characterization of roots of order-statistics filters are also proposed. >
