video canceller 中文意思是什麼
-
To solve the tradeoff between congverence and computational complexity, befap is proposed in chapter 3, which is based on block - exact processing and affine projection algorithm. chapter 4 offers hardware and software implementation of the acoustic echo canceller based on tms320vc5409 dsp, which can be applied to a terminal of the tele - conference or video - conference
為了在收斂速度和運算量之間得到很好的折中，第三章提出了一種基於仿射投影演算法和精確塊技術的快速的自適應演算法（ befap演算法） ，並對該演算法作了詳細的分析和研究。 -
Tele - conference, video - conference. acoustic echo cancellation is normally achieved by means of an acoustic echo canceller, which, in its simplest form, consists of an adaptive filter which mimics the transfer function of the echo path ( or room acoustic ) to synthesize a replica of the echo, and then subtracts the estimation from the combined echo and near - end speech ( or disturbance ) signal to obtain the near - end signal alone
聲回波抵消通常採用聲回波抵消器來實現，最簡單的聲回波抵消器由自適應濾波器組成。具體方法是用自適應濾波器來估計回波信號，並從麥克風信號中減掉該估計值，從而實現聲回波的抵消。
