Abstract
Abstract A novel time-frequency technique for linear and nonlinear frequency modulated signal denoising is proposed. The proposed method is based on the principle of Quasi Fourier Transform (QTF). Firstly, we discusses in depth the principles and properties of QFT theoretically. Secondly, by applying the QFT, Multi-component signal with aliasing in frequency domain is separated successfully, and it is readily to de-noise for linear or nonlinear frequency modulated signals with white or 1/f noise. Thirdly, related issues such as the resolution and the effect of noise are studied. The simulation results show that QFT is an efficient tool to extract effectively useful signals from buried in the noise.
