摘要
分析了时域及变换域LMS自适应滤波器的设计,提出了一种基于分数阶Fourier域的LMS自适应滤波算法,并推导了基于离散分数阶Fourier变换的计算方法.
This paper analyze the design about LMS adaptive filter, gives a new LMS adaptive filter algorithm based on fractional fourier transform, and a new method for calculating discrete fractional fourier transform based on the adaptive LMS algorithm is proposed.
