An Integer Approximation Method for Discrete Sinusoidal Transforms

5 Jul 2020R. J. Cintra

Approximate methods have been considered as a means to the evaluation of discrete transforms. In this work, we propose and analyze a class of integer transforms for the discrete Fourier, Hartley, and cosine transforms (DFT, DHT, and DCT), based on simple dyadic rational approximation methods...
