ABSTRACT:
A technique for computationally efficient evaluation of the Modified Discrete Cosine Transform (MDCT) using the Fast Fourier Transform (FFT) method is presented in which the input of the FFT block consists of a sequence of N complex numbers, and this complex data is evaluated using an N/2-Point FFT only, thereby descreasing computation burden almost by two.
