There is a close relationship between the conventional Discrete Cosine Transform (DCT) and Discrete Fourier Transform (DFT). Here, we introduce another transform, the Discrete Fractional Cosine Transform (DFrCT), which has a similar relationship with the Discrete Fractional Fourier Transform (DFrFT). The DFrCT share many useful properties of the regular cosine transform, and has a free parameter, its fraction. When the fraction is zero, we get the cosine modulated version of the input signal… CONTINUE READING
