Abstract(in Japanese) (See Japanese page)
Abstract(in English) Adaptive algorithm plays the important role in adaptive signal processing,and much work has been proposed various techniques until up to now.Among them,the orthogonal projection algorithm are well known,which can be expressed with Moore-Penrose type generalized inverse matrix.It can have rapid convergence speed no matter how input signal are correlated.But,the direct calculations of Moore-Penrose type generalized inverse matrix,need much computational complex.This paper presents the adaptive algorithm in which Moore-Penrose type generalized inverse matrix can be efficiently calculated with UD factorization.The proposed algorithm is expected to have stable property,since it includes only one division in the procedures.As well,proposed method have a condition to provide which kave stable convergence characteristics when noise to exist.Proposed algorithm expressed a basic properties,and show effective this algorithm.
