Abstract
An adaptive filtering algorithm using fractional Fourier transform is proposed. In this method, the input signals are first transformed to fractional Fourier domain and then filtered adaptively in this domain. Analyses and simulation results show that, compared with frequency domain LMS adaptive filter, remarkable improvements of convergence.
