基于Rayleigh分布曲线的混合权系数变步长LMS算法
Variable step-size LMS algorithm with hybrid weight coefficients based on the Rayleigh distribution curve
摘要
Abstract
Due to the limitations of existing variable step-size LMS adaptive filtering algorithms in addressing conver-gence speed,tracking performance,and steady-state errors,a variable step-size LMS algorithm with hybrid weight coeffi-cients based on the Rayleigh distribution curve was proposed.The impact of the new variable step function parameters α,β,γ and the hybrid filter weight coefficient W(n)on the proposed algorithm performance and interference suppression analysis were discussed in detail.Simulation and experimental results demonstrate that the proposed algorithm reduces computational complexity while improving convergence speed by at least 12%.Moreover,it exhibits superior conver-gence speed,tracking performance,and steady-state errors across various signal-to-noise ratios.The proposed algorithm is suitable for electromagnetic interference cancellation in complex environments.关键词
