In this project, we have designed and implemented a method to estimate the dual frequencies in sinusoids immersed in additive white Gaussian noise. The Cramér-Rao lower bound (CRLB) for the signal model and a nonlinear least square frequency estimator are derived. The estimator is evaluated by numerical examples.
