摘要
研究了利用分层双线性滤波器实现ＤＭＴＡＤＳＬ（ 离散多频音不对称数字用户线） 中非线性回波抵消的方案，提出了利用检测处理加速迭代收敛的方法。
A study is conducted on the scheme of nonlinear echo cancellation in DMT ADSL,which is implemented by means of the adaptive layered bilinear filter.A check processing method to accelerate the iteration convergence is then proposed.Finally,the corresponding computer simulation results are given.
