Popis: 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 L p norm minimization. The effectiveness of outer product expansions for artificial signals was represented in the conventional reports. The L 1 norm minimization has a problem in the estimation performance. The outer product expansion with lower norms (0.1 ∼ 0.9) showed a better estimation than L 1 norm. However, the estimation stability might not be performed by using conventional method. We show that the estimation accuracy and stability for L p norm minimization and its developed solution.
