Abstract(in English) In recent years,information network system suitable for fast data transmission.Adaptive signal processing technology is needed to perform efficient these system.With the progress of the signal processing technology,the development of adaptive algorithm have been important more and more.In the development of adaptive algorithm is needed mainly(1)the improvement of convergence speed, (2)the reduction of computational requirement,etc. Well,the usage of block signal processing be attempted as the method to realize(1),(2).Block processing is the technique which adjust filter′s coefficients block unit per.This is expected to be able to realized the improvement of convergence speed and the reduction of computational requirement per sample time.This paper presents a new method of linear equation based on the gradient method.Next,the fundamental properties of the proposed algorithm, such as the relationship between the block length and convergence characteristic,are analytically discussed.Finally,computer simulations for performance evaluation are presented.
