Estimation algébrique des paramètres intrinsèques d'un signal sinusoïdal biaisé en environnement bruité

2011

The amplitude, frequency and phase of a biased and noisy sinusoidal signal are estimated via algebraic techniques. The methods which are popular today seem unable to obtain a robust estimation of those parameters within a fraction of the signal's period. The e ciency of our approach is illustrated by several computer simulations.
