block-diagonalizationとは 意味・読み方・使い方

A communication partner selecting circuit 108 estimates a frequency utilization efficiency in using the BD (Block Diagonalization) method and determines a combination of communication partners with an improvement larger than that in the single user communication.例文帳に追加

通信相手選択回路１０８は、ＢＤ法を用いた際の周波数利用効率を推定し、シングルユーザ通信時より改善が大きい通信相手の組み合わせを決定する。 - 特許庁

After short-time discrete Fourier transform of an observation signal multiplied by a window function, an inverse matrix of a spatial correlation matrix of the observation signal weighted by the way of an exponential function is determined in each block, and a plurality of blocks are used as objects for the least-squares type simultaneous diagonalization problem.例文帳に追加

窓関数を乗算した観測信号の短時間離散フーリエ変換後、指数関数的に重み付けられた観測信号の空間相関行列の逆行列をブロック毎に求め、複数のブロックを最小２乗型同時対角化問題の対象にする。 - 特許庁
