In 1795, Gaspard de Prony [1] proposed a method to explain the expansion of gases as a linear sum of damped complex exponentials of signals that are uniformly sampled. Prony’s method approximates a sequence ofN= 2p equally spaced samples to a linear combination of p complex exponential f...
Thus, a given frequency estimator may be portrayed as very accurate when operating with a cisoid under noise contamination, but its performance may drop significantly when operating with real-valued sinusoids, or even degrade critically under the influence of other co-existing sinusoids; namely, ...
