| Abstract(in English) | This paper shows a new denoising algorithm based on the outer product expansion with Modified Trimmed Mean (MTM) for the background noise. We have proposed novel source separation methods using the outer product expansion with non-linear filters. The effectiveness of outer product expansions for artificial signals and an electromagnetic wave data was represented. As for an outer product expansion based denoising algorithm, the MTM method with a small trimming distance provides the accurate background noise reduction. However, the denoising performance is not improved enough when the trimming distance is too small. In this paper, the new background noise estimation technique which calculates the MTM recurrently with a small threshold and its solution algorithm are proposed. Simulation results shows that the proposed method produces the accurate background noise reduction. |
