As a result, BER degradation of unexpected multi-path waves with over guard interval time, adjacent channel interference and large level changes of electric field that are characteristics of mobile ship reception occurred. Therefore, shielding of undesired waves using the ship structure and selection of receiving antennas according to electric field strength and so on are taken. By these methods, digital TV waves can be received at almost all lines and one segment reception can be available at whole cabin of a ship.","subitem_description_type":"Abstract"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_3_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110006549501","subitem_relation_type_select":"NAID"}}]},"item_3_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3169/itej.63.76","subitem_relation_type_select":"DOI"}}]},"item_3_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"CiNii Research"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://cir.nii.ac.jp/crid/1520009409507876352","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"J-STAGE"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/article/itej/63/1/63_1_76/_article/-char/ja/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"情報処理学会電子図書館"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://ipsj.ixsq.nii.ac.jp/ej/?action=pages_view_main&active_action=repository_view_main_item_detail&item_id=41043&item_no=1&page_id=13&block_id=8","subitem_relation_type_select":"URI"}}]},"item_3_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。"},{"subitem_rights":"The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
