چکیده
Abstract: In this letter, an efficient algorithm for three-dimensional (3-D) vector radix decimation in frequency is derived for computing the type-III 3-D discrete W transform (DWT). Comparison of the computational complexity with the familiar row-column algorithm shows that the proposed approach reduces significantly the number of arithmetic operations. Moreover, the proposed method has very regular structure, thus, it is easy to implement.

متن کاملAn Algorithm for Computing the Radix - 2 n Fast Fourier Transform
In digital signal processing, the Fast Fourier Transform (FFT) is a kind of high efficient method to calculate the discrete Fourier transform (DFT). It cuts the discrete signal sequence which the length is N for different radix sequences to operate using the way of handing back and partition. Currently, the radix-2 FFT algorithm is a popular approach to do the transform work. However, its compu...

—Recently, a fast radix-algorithm for an efficient computation of the type-IV discrete cosine transform (DCT-IV) has been proposed in [1], where is an odd positive integer. In particular, based on the proposed fast algorithm, optimized efficient 3-, 5-, and 9-point scaled DCT-IV (SDCT-IV) modules have been derived in [1]. As a response, an improved efficient optimized 9-point scaled DCT-IV (SDC...
