An adaptive and computationally efficient algorithm for parameters estimation of superimposed exponential signals with observations missing randomly
TL;DR: An adaptive and computationally efficient iterative algorithm is proposed to estimate the frequencies of a model of superimposed exponential signals in multiplicative and additive noise when some observations are missing randomly and the refined estimators by three iterations are observed to be asymptotically unbiased and consistent.
