Delta算子作为一种新的离散化方法引入自适应滤波器,提出了一种基于算子的自适应LMS算法。并把基于Delta算子的LMS算法法应用到于噪声抵消中,取得了优于传统的移位算子的收敛速度和稳态失调。
As a new discretization method, Delta operator is introduced into adaptive filter and an operator-based adaptive LMS algorithm is proposed. The LMS algorithm based on Delta operator is applied to the noise cancellation, and the convergence rate and steady-state offset are obtained better than the traditional shift operator.
