In this paper a novel MDCT without multiplications has been presented via transforming it into the computation of the
first-order moment. Then the method proposed for computing moments has been adapted to implement the arbitrary-length
MDCT efficiently. A very simple and scalable systolic array without multipliers and ROMs has also been
designed to perform the MDCT, which can result in the efficient VLSI implementation easily. And the comparison with
some existing methods shows the superiority of our method.
