抄録
内容記述タイプ Abstract
内容記述 M2M (Machine to Machine)通信の需要拡大に伴い,小パケットで多数のユーザが同時通信可能な無線通信システムの実現が求められており,ユーザに個別のインターリーバを割り当てて多重伝送するIDMA (Interleave-DivisionMultiple-Access)が検討されている.OFDM-IDMA方式にアンテナダイバーシチや繰り返し復号を適用したときの受信機構成について検討し,計算機シミュレーションにより通信特性を評価する.受信機側のIDMAの干渉除去処理においてダイバーシチのブランチ合成と誤り訂正後の情報を用いた尤度値の符号補正を行うことでマルチパスフェージング環境下での通信特性を改善できることを明らかにした.

内容記述タイプ Other
内容記述 To meet the growing demand for machine to machine (M2M) communication, the realization of simultaneous communication in many users are requested. Interleave-division multiple-access (IDMA) has been investigated that allocates users to specific interleave patterns. We study a receiver structure where antenna diversity and iterative decoding are applied in an OFDM-IDMA system and evaluate its communication performance using computer simulations. 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.
