Abstract

In this paper, the Cramér-Rao Lower Bound on the estimation of the parameters of a noisy sinewave based on quantized data is discussed. The effects of overloading noise and Integral Non-Linearity are considered and modeled, assuming both coherent and non-coherent signal sampling. It is shown that a simplified model can be derived, which describes the Cramér-Rao Lower Bound by considering only the most frequently excited ADC transition levels. Then the effects of quantization on the Sinewave Fitting statistical efficiency are investigated
