Abstract

Harmonic retrieval is one of the most frequently encountered problems in practice, and constitutes a significant part of statistical signal processing research. The concern here is retrieval of multiple tone harmonics observed in white Gaussian multiplicative and white complex Gaussian additive noise. Computable Cramer-Rao bound (CRB) expressions are derived on the frequency and phase estimates as well as on the sample mean of the multiplicative noise processes. Numerical studies support the obtained results
