ADAPTIVE SCHEME FOR OVERSAMPLED FRONT ENDS

Olli Vainio
  • Abstract:
    A computationally efficient adaptive filtering scheme for oversampled A/D converters is discussed. The decimating digital filter is constructed as a combination of a sinc decimator and an adaptive predictor. A reduced-rank adaptive algorithm with two adaptive parameters is proposed for this purpose avoiding the complexity of the commonly used full-rank algorithms. The characteristics of the adaptive filter are considered, and a comparative example of data signal processing is shown.
