Nonlinear Least-Squares Approach to Freq

In this paper, we consider the problem of estimating the frequency of a sinusoidal signal whose amplitude could be either constant or time-varying. We present a nonlinear least-squares (NLS) approach when the envelope is timevarying. It is shown that the NLS criterion can be explicitly minimized wit
