The conventional method that performs wordlength selection based on the number of successful packet receptions tends to be slow in wordlength tracking operation and degrade communication performance in time-variable multipath fading environments. The proposed method performs wordlength selection using minimum value information of subcarrier SNRs and solves the problem of tracking operation. In the results of evaluating communication performance and power consumption, the proposed method provided the same communication performance as the use of fixed-wordlength and reduced power consumption by 32% and 22% for QPSK and 16QAM demodulations.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_5_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u96fb\u5b50\u60c5\u5831\u901a\u4fe1\u5b66\u4f1a", "subitem_publisher_language": "ja"}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "c2013 by IEICE"}]}, "item_5_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0913-5685", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "\u30a2\u30af\u30bb\u30b9\u6a29", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u4f50\u3005\u6728, \u5927\u5730", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "89924", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u5409\u6fa4 , \u771f\u543e", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "298", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "20447080", "nameIdentifierScheme": "KAKEN -
