Abstract
In this paper we derive a new recursive algorithm for the discrete cosine transform (RDCT) which differs from the existing RDCT in the following aspects: (1) No shifts of data are required within our algorithm; (2) only regular Cooley-Tukey type butterfly structures are involved; (3) the multiplication coefficients in our algorithm can be generated by a simple recursion without a requirement for trigonometric functions. The structure of the new algorithm is almost identical to that of Lee's FCT, which is widely thought to be the simplest.>
