Table Look-Up Estimation of Signal and Noise Parameters From Quantized Observables
Victor A. Vilnrotter, Eugene R. Rodemich · NASA STI Repository (National Aeronautics and Space Administration) · 1986
A table look-up algorithm for estimating underlying signal and noise parameters from quantized observables is examined. A general mathematical model is developed, and a look-up table designed specifically for estimating parameters from four-bit quantized data is described. Estimator performance is evaluated both analytically and by means of numerical simulation, and an example is provided to illustrate the use of the look-up table for estimating signal-to-noise ratios commonly encountered in Voyager-type data.
