Abstract :
Fast algorithms for running the even discrete cosine transform (EDCT) and the even discrete sine transform (EDST) are presented in this paper. The computational complexity and stability are analyzed. The algorithms given here gain considerable computational savings compared with the direct algorithms, thus can effectively find applications in real-time signal processing
