STBC-OFDM方式は信頼性の高い通信を実現する上で重要な無線通信技術の一つと考えられる．STBC復号を行うためには，受信機側で送受信アンテナ間のチャネル推定が必要であり，誤り率特性の向上のために高い精度のチャネル推定方式が求められている．本論文では，LDPC符号化MIMO-STBC- OFDMシステムにおいて，LDPC復号後の軟判定値による帰還を用いた繰返しチャネル推定方式を提案している．提案方式では，LDPC復号後の復号データを用いて信頼度の高い送信信号の軟値レプリカを生成し，それを用いてチャネル推定を繰り返し行うことで，推定精度の向上を図っている．計算機シミュレーションにより提案方式の有効性を明らかにした．","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"familyNames":[{"familyName":"Iwanami","familyNameLang":"en"},{"familyName":"岩波","familyNameLang":"ja"},{"familyName":"イワナミ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Yasunori","givenNameLang":"en"},{"givenName":"保則","givenNameLang":"ja"},{"givenName":"ヤスノリ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"8579","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Iwanami,
