Echo Cancellation System with Dual Adaptive Filter and Effect of Multiplication Factor in LMS Algorithm Weight Equation
Abstract
The paper presents a Novel concept of application of dual adaptive filter in modeling of an echo cancellation system for active noise cancellation. It also investigates the robustness and practicability of the proposed model by analyzing the convergence rate, adaptability, step size requirements and closeness to desired output in comparison with conventional single filter model. The effect of adding a multiplication factor in the weightequation of the Least Mean Square (LMS) algorithm is analyzed and a new concept is proposed. Simulation and theoretical results indicate better performance and good filtering results as compared to conventional model.
