Abstract: In this paper we propose using the correlated cosine structure (CCS) for the computation of the discrete cosine transform (DCT). This structure has circulant property and is most suitable for the hardware realization. We will show that there exists a close relationship between the CCS and the DCT. In such a case, a 2[sup m] length DCT can be decomposed recursively into shorter length CCS and DCT. This new approach results in very simple and straightforward structure and gives the minimum number of multiplications for its realization.
