Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we establish a relationship between the widely-studied
reduced-rank adaptive filtering and the recently developed technique
based on quadratic-metric projection, which is a best
approximation of an arbitrary point in a closed convex subset of a
real Hilbert space with respect to a quadratic-norm.
Based on the relations, we present a way to bring the information used
in the reduced-rank adaptive filtering to the design of the
quadratic-metric, which is the key factor to determine the convergence
rate of the quadratic-metric projection techniques.
The quadratic-metric projection method is more robust in the case that
the information to design the rank-reduction matrix has uncertainty,
as demonstrated by numerical examples in the application to interference
suppression in DS/CDMA wireless communication systems.
