Abstract(in English)	This paper proposes a method of background noise estimation based on outer products and a median. We showed that an outer product expansion with absolute error method is effective to estimate a background noise, however, background noise is might be estimated when the number of signal is limited. In this paper, we show that the approximate accuracy is improved by using proposed method.
