Compared with the traditional adaptive feedback suppressor, this system has been added a new component, the residual echo suppressor component. 与传统的自适应的方法比较,增加了系统识别和驻波抑制的相关模块,一定程度的提高了传声增益。
The theoretical analysis and estimation methods of subband least square filter based on multichannel echo suppressor are given. This method has stronger self-adaption ability, rapid algorithm convergence and high control accuracy. 提出了一个基于多信道回声消除器的子带最小二乘滤波器理论分析和估算方法,该方法具有较强的自适应能力、算法收敛快、控制精度高。
