作者在文献〔4〕中提出了一种改进的瞬变步长 SPL MS自适应滤波算法。本文在 SPL MS算法的基础上 ,进一步提出一种基于瞬变步长、瞬变平滑因子的双瞬变 SPL MS算法— DSPL MS算法。该算法除具有常规 L MS算法简单的优点外 ,还具有更高的起始收敛速率、更小的权失调噪声和更大的抑噪能力。文中重点讨论瞬变步长、瞬变平滑因子的变化特性。计算机仿真结果支持了理论分析
In [4], the author proposed an improved SPL MS adaptive filtering algorithm for transient steps. Based on the SPL MS algorithm, this paper proposes a double-transient SPL MS algorithm based on transient steps and transient smoothing factors - DSPL MS algorithm. In addition to the simple advantages of the conventional LMS algorithm, this algorithm also has higher initial convergence rate, smaller noise of the offset and greater noise suppression. In this paper, we focus on the characteristics of transient step and transient smoothing factor. Computer simulation results support the theoretical analysis
