Fig. 1.1: Comparison of Execution Times, DFT & Radix – 2 FFT The radix-2 decimation-in-frequency FFT is an important algorithm obtained by the divideand-conquer approach. The Fig. 1.2 below shows the first stage of the 8-point DIF algorithm. Fig. 1.2: First Stage of 8 point Decimation...
The three-dimensional discrete Hartley transform (3-D DHT) hasbeen applied in a wide range of 3-D applications such as 3-D powerspectrum analysis, 3-D filtering, and medical applications, etc. Inthis paper, a three-dimensional algorithm for fast computation of thethree-dimensional discrete Har...
