Abstract(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.
