摘要: A discrete cosine transform (DCT) is described and a technique to compute it using fast Fourier (FFT) developed. In this work, DCT of finite length sequence obtained by incorporating CORDIC methodology in radix-2 FFT algorithm. The proposed simple comprehend maintains regular structure, thereby reducing computational complexity. DCTs are used extensively the area digital processing for purpose pattern recognition. So efficient computation maintaining transparent design flow highly solicited.
