Abstract
,In this correspondence, we show that the discrete cosine transform (D CT) can be obtained by projecting the discrete Fourier transform from the extension field to the basefield, Applying the framework of projec tion operator, a fast fully recursive algorithm For computing the DCT is also presented.
