Signal Analysis Based on A Synthetic Method of Wavelet Transform and Fourier Transform
Peng Wang · Information Security and Communications Privacy · 2007
In this paper a synthetic method of wavelet transform and Fourier transform is presented.Signal is first decomposed by wavelet transform.Then one can get each sub-band signals? spectrum by fast Fourier transform.Computer simulations show that this method possesses the combined merits of wavelet transform and Fourier transform.
