The method proposed in , referred to as iterative Quasi-Harmonic Model (iQHM), is an iterative frequency estimation technique. It is based on a linearized version of the frequency error between the true frequency and the initially provided frequency, while the estimation of its unknown parameters is performed by Least Squares (LS) method. In , a relationship between iQHM and Gauss-Newton (GN) method was presented. More specifically it was claimed that iQHM is actually equivalent to an approximate Gauss-Newton method (AGN). In this correspondence, we show that iQHM is actually equivalent to a sequential version of the GN method.
