Description

ユーザセレクタユニット1102は、フィードバックユニット1112によって得られたフィードバック情報に基づいて、複数のユーザU1−UMに関連のデータを選択し、複数の符号化変調ユニット1104の各々にこの情報を提供する。各符号化変調ユニット1104は、ユーザの情報ビットを符号化及び変調してマッピングユニット1106に送る。マッピングユニット1106は、複合記号、即ち、複数のシンボル集合体に入力ビットをマップし、DIDO−IQ認識プリコーディングユニット1108に結果を送る。DIDO−IQ認識プリコーディングユニット1108は、ユーザからフィードバックユニット1112によって得られたチャネル状態情報を利用してDIDO−IQ認識プリコーディング重みを計算し、マッピングユニット1106から得られる入力記号をプリコーディングする。プリコーディングデータストリームの各々は、IFFTを計算して循環プレフィックスを追加するOFDMユニット1115にDIDO−IQ認識プリコーディングユニット1108により送られる。この情報は、DA変換を操作してRFユニット1114に送るD/Aユニット1116に送られる。RFユニット1114は、中間/高周波にベースバンド信号をアップコンバートして送信アンテナに送る。
ユーザセレクタユニット1902は、DIDO構成器1910によって得られるフィードバック情報に基づいて、複数のユーザU1−UMに関連のデータを選択して複数の符号化変調ユニット1904の各々にこの情報を提供する。各符号化変調ユニット1904は、各ユーザの情報ビットを符号化及び変調してマッピングユニット1906に送る。マッピングユニット1906は、複合記号、即ち、複数のシンボル集合体に入力ビットをマップしてプリコーディングユニット1908に送る。符号化変調ユニット1904及びマッピングユニット1906は、DIDO構成ユニット1910から得られた情報を利用して各ユーザに対して使用すべき変調/符号化方式の形式を選択する。この情報は、フィードバックユニット1912によって供給される各々のユーザのチャネル品質情報を利用することによってDIDO構成ユニット1910により計算される。DIDOプリコーディングユニット1908は、DIDO構成ユニット1910によって得られる情報を利用してDIDOプリコーディング重みを計算し、マッピングユニット1906から得られる入力記号をプリコーディングする。プリコーディングデータストリームの各々は、IFFTを計算して循環プレフィックスを追加するOFDMユニット1915にDIDOプリコーディングユニット1908により送られる。この情報は、DA変換を操作してRFユニット1914に得られるアナログに信号を送るD/Aユニット1916に送られる。RFユニット1914は、中間/高周波にベースバンド信号をアップコンバートして送信アンテナに送る。
