INFLUENCE OF QUANTIZATION NOISE ON DFT–BASED DSP ALGORITHMS

Martin Novotný, Miloš Sedláček
  • Abstract:
    This paper deals with analysis of influence of quantization noise on estimation of parameters of signal gained by various algorithms based on Discrete Fourier Transform (DFT) for the case of coherent and non–coherent sampling. Theoretical analysis, numerical simulation results and experimental validation are presented. The analyzed methods are compared from the point of view of their sensitivity to quantization noise.
