一种基于格型算法的线谱增强器

An Adaptive Line Enhancer using IIR

利用格型算法的线谱增强器与自适应FIR陷波器相比,不仅运算量大大降低,而且避免了FIR陷波器中去噪声相关时延Δ的选择,这两点十分有利于工程实现。利用变步长的自适应线谱增强器可以大大增加收敛速度。计算机仿真结果证明了这一点。

IIR adaptive line enhancer（ALE） is better than FIR ALE, not only computation is greatly reduced, but also avoid the FIR notch filter to the noise correlation time delay selection. Adaptive line enhancer variable step-size use can greatly increase the convergence speed. Simulate result proved it.
