改进的变误差宽度变阶数LMS算法
Improved variable error width variable fractional tap-length LMS algorithm
摘要
Abstract
In order to solve the order mismatch problem of the adaptive filter,an improved variable error width variable fractional tap?length LMS algorithm is proposed. The parameter selection of the error width function isn′t limited by the noise prior knowledge in the algorithm,and its foundation is given. The simulation analysis are performed for the algorithm under the envi?ronments of low noise,high noise and changing noise. The simulation results show that the algorithm can be applied to the envi?ronments of the unknown system noise or changing noise,has good performance,can obtain fast order convergence rate and small steady?state error in high noise environment,and its applications are extensive.关键词
