2D Sinusoidal Parameter Estimation with Offset Term

Abstract: We consider the parameter estimation of a 2D sinusoid. Although sinusoidal parameter estimation has been extensively studied, our model differs from those examined in the available literature by the inclusion of an offset term. We derive both the maximum likelihood estimation (MLE) solution and the Cramer-Rao lower bound (CRLB) on the variance of the model's estimators.
