NLMsとは 意味・読み方・使い方

The coefficient update control part 43 may switch the coefficient update processing so as to reduce the convergence rate; for example, it may switch from the RLS (Recursive Least-Square) method to the NLMS method.例文帳に追加

係数更新制御部４３は、収束速度が低下するように係数更新処理を切り替えてよく、例えばＲＬＳ法からＮＬＭＳ法へ切り替えてよい。 - 特許庁

An echo canceler function part 28 is composed of hardware and an adaptive filter based upon its NLMS algorithm is so constituted that its filter coefficient ω is found by performing normalization processing by previously computing the reciprocal number (1/A) of a square norm regarding a vector series of an output sound signal and performing multiplication by the reciprocal number as to each tap of the filter.例文帳に追加

エコーキャンセラ機能部２８をハードウエアで構成し、そのＮＬＭＳアルゴリズムに基づく適応フィルタを、出力音響信号のベクトル系列に関する２乗ノルムの逆数（１／Ａ）を予め演算し、フィルタの各タップについて前記逆数を乗じることで正規化処理を行い、フィルタ係数ωを求めるように構成する。 - 特許庁
