摘要: The aim of the paper is to propose an adaptive method for filtering linear FM signal embedded in white Gaussian noise. proposed approach based on idea that fractional Fourier transform a equivalent rotating time-frequency plane. performance evaluated terms computational complexity and SNR improvement factor. Some theoretic analysis simulation results are included demonstrate validity method. show remarkable tolerable distortion obtained and, compared with two other dimension algorithms, easy computation simple implementation.
