Description: 這篇論文提出了一個在網路電話上處理回音消除的架構，並考量到雙邊通話提出了改進的演算法。-a model for electrical echo in
telephone networks for varied echo-path delay was
designed. This was with a view to implementing an
adaptive electrical echo canceller based on a
combination of the Normalized Least Mean Square
(NLMS) and Geigel speech detector algorithms (GSD).

Description: 在一种变步长算法基础上, 从语音信号相关性的角度出发, 提出了一种新的去相关变步长LMS 算法( DCL—NLMS) 。该算
法结构简单, 收敛速度快, 稳态失调小, 计算量与NLMS 算法相当。仿真结果表明, 该算法在处理强相关性信号时, 不仅收敛速度明
显快于其余算法, 而且稳态失调特性也有很大优势-Based on the variable step NLMS arithmetic, this paper proposes a new uncorrelated variable step arithmetic( DCL—
NLMS) by employing auto—correlation of the input speech signal.The proposed algorithm has simple structure, fast convergence
speed, but small stability maladjustment with the same computational complexity as NLMS.Simulation results show not only its
convergence is faster than that of the others, but also the stable maladjustment of it is better too.
