Interleave-division multiple-access (IDMA) has been investigated that allocates users to specific interleave patterns.

The receiver combines diversity branches and compensates for signs of likelihood values from bit information after error correction in interference cancellation of IDMA. It improves communication performance the OFDM-IDMA system under multipath fading.", "subitem_description_type": "Other"}]}, "item_5_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u4e00\u822c\u793e\u56e3\u6cd5\u4eba\u96fb\u5b50\u60c5\u5831\u901a\u4fe1\u5b66\u4f1a"}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a92015 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": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u7530\u5cf6, \u831c"}], "nameIdentifiers": [{"nameIdentifier": "89936", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u5409\u6fa4 , \u771f\u543e"}], "nameIdentifiers": [{"nameIdentifier": "298", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "20447080", "nameIdentifierScheme": "KAKEN -
