Abstract

The author presents efficient architectures for implementing the discrete Fourier transform (DFT) and the discrete Hartley transform (DHART) based on prime factor decomposition. He uses the multiplierless distributed arithmetic in this architecture. The lookup table sizes needed for implementing the short DFT/DHART modules are minimized by judiciously decomposing the short DFT/DHART matrices.
