Fast radix-\(p\) discrete cosine transform
A fast algorithm of the discrete cosine transform (DCT) of radix-\(p\) and its inverse are presented. Their architecture comprises the divide-and- conquer operations and the arithmetic with Chebyshev polynomials. This algorithm is efficient in DCTs of arbitrary transform length and applicable for discrete Vandermonde transforms.
