Error rate performance is degraded due to severe channel fading. Forward error correction (FEC), automatic repeat request (ARQ) or diversity reception techniques are occasionaly employed to reduce the effect of fading. FEC with interleaving provides good error performance in a fading channel, but expands bandwidth, and consequently degrades spectral efficiency. This problem is solved without changing bandwidth efficiency by integration of an error correction coding with a bandwidth-efficient modulation scheme, namely a coded-modulation technique. In this paper the word error probabilities of Reed-Solomon coded 16-level star QAM schemes in a land mobile radio channel are evaluated based on computer simulations. The receiver uses differential detection and two different decoding strategies, errorsonly and erros-and-erasures decoding. It is estimated that large coding gain is achieved using these coded-modulation techniques. More coding gain is obtained using errors-and-erasures decoding.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00033244","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Information and Computer Engineering, Faculty of Engineering, Okayama University of Science"},{"subitem_text_language":"en","subitem_text_value":"Department of Information and Computer Engineering, Faculty of Engineering, Okayama University of Science"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"岡山理科大学工学部情報工学科"},{"subitem_text_language":"ja","subitem_text_value":"岡山理科大学工学部情報工学科"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1996-03-31"}],"displaytype":"detail","filename":"KJ00000063671.pdf","filesize":[{"value":"413.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://ous.repo.nii.ac.jp/record/1162/files/KJ00000063671.pdf"},"version_id":"aaa50880-a015-43d2-9ff8-7e1a94f298f1"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"移動体通信における Reed-Solomon 符号化16値スター QAM 方式の誤り率特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"移動体通信における Reed-Solomon 符号化16値スター QAM 方式の誤り率特性","subitem_title_language":"ja"},{"subitem_title":"Error Performance of Reed-Solomon Coded 16-level Star QAM in a Land Mobile Radio Channel","subitem_title_language":"en"},{"subitem_title":"イドウタイ ツウシン ニオケル REED SOLOMON フゴウカ 16チ スター QAM ホウシキ ノ アヤマリリツ トクセイ","subitem_title_language":"ja-Kana"}]},"item_type_id":"1","owner":"14","path":["329"],"pubdate":{"attribute_name":"PubDate","attribute_value":"1996-03-31"},"publish_date":"1996-03-31","publish_status":"0","recid":"1162","relation_version_is_last":true,"title":["移動体通信における Reed-Solomon 符号化16値スター QAM 方式の誤り率特性"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2023-09-28T04:56:27.519978+00:00"}
