摘要：
A novel method of Quasi Fourier Transform for reconstruction of multi-component signals is presented, which the characteristics and properties of this method axe investigated. By transforming the various aliasing signals in frequency domain into a quasi frequency domain, the multi-component signals can be easily separated. Some contrasts of Quasi Fourier Transform compared with fractional Fourier domain filtering can avoid some problems of aliasing distortion in time domain and frequency domain. The results by citing specific examples show that Quasi Fourier Transform will be an efficient tool to extract effectively useful signals from buried in the noise.
