世代移動通信システム（5G）では，超高速・高品質を達成するためにMU-MIMO の利用が\n検討されている．また，ミリ波等の高周波数帯利用による伝搬損失を補償するためMassive MIMO の導入が想\n定されている．しかし，基地局アンテナの大規模化やユーザ数の増加によってMU-MIMO 制御のための計算量\nの増大が課題となる．本論文では，伝搬チャネル行列の一般逆行列を用いてブロック対角化を実現し，空間的に\nユーザの多重化を行うMU-MIMO のための線形制御法を提案する．提案法では，特異値分解による雑音部分空\n間の演算を省略するThin SVD を用いて計算量を削減している．また，MU-MIMO の制御として用いられる\nBD
