精确块 meaning in Chinese

accuracy block

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
为了在收敛速度和运算量之间得到很好的折中，第三章提出了一种基于仿射投影算法和精确块技术的快速的自适应算法( befap算法) ，并对该算法作了详细的分析和研究。
