Accuracy Analysis of Background Noise Estimation Using Outer Product Expansion with Lower Norm
Kouta Sugiura, Akitoshi Itai (Chubu Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, the background noise estimation using outer product expansion is developed.
We have shown that a possibility of blind source separation based on an outer product expansion with $mbox{L}_{mbox{scriptsize p}}$ norm minimization. The effectiveness of outer product expansions for artificial signals was represented in the conventional reports. The $mbox{L}_{mbox{scriptsize 1}}$ norm minimization has a problem in the estimation performance. The outer product expansion with lower norms (0.1 $sim$ 0.9) showed a better estimation than $mbox{L}_{mbox{scriptsize 1}}$ norm. However, the estimation stability might not be performed by using conventional method. We show that the estimation accuracy and stability for $mbox{L}_{mbox{scriptsize p}}$ norm minimization and its developed solution.
