We have proposed novel source separation methods using the outer product expansion with L1 norm minimization. Effectiveness of outer product expansions for artificial signals and an electromagnetic wave data was represented. However, the denoising performance is decreasing with an increasing of local signals. In this paper, we propose the outer product expansion with lower norms (0.1 ∼ 0.9). Simulation results show that the proposed method produces the accurate background noise reduction.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌: \u003c\/strong\u003e\u003ca href=\"\/products\/ieej-rc13612\"\u003e電気学会論文誌C（電子・情報・システム部門誌） Vol.136 No.12 （2016） 特集Ⅰ：電気・電子・情報関係学会東海支部連合大会　特集Ⅱ：国際会議ACIS 2014\/2015\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌掲載ページ: \u003c\/strong\u003e1691-1692 p\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e原稿種別: \u003c\/strong\u003e研究開発レター／日本語\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e電子版へのリンク: \u003c\/strong\u003e\u003ca target=\"_blank\" href=\"https:\/\/www.jstage.jst.go.jp\/article\/ieejeiss\/136\/12\/136_1691\/_article\/-char\/ja\/\"\u003ehttps:\/\/www.jstage.jst.go.jp\/article\/ieejeiss\/136\/12\/136_1691\/_article\/-char\/ja\/\u003c\/a\u003e\u003c\/p\u003e","brand":"IEEJ-P09","offers":[{"title":"冊子印刷（一般価格550円\/会員価格330円） \/ A4 \/ 2","offer_id":46349976010991,"sku":"IEEJ-RC13612-012-PRT","price":550.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-RC13612_5726cade-e1f2-4797-8ee6-f225ffdaf260.png?v=1743166751","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-rc13612-012","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
