In this paper, it is assumed that the desired signal f1(t) is a harmonic complex tone, where F0(t) is the fundamental frequency. The proposed model segregates the desired signal from the mixed signal by constraining the temporal differentiation of Ak(t), $\theta_{1k}(t)$, and F0(t).

The proposed model is composed of four blocks: an auditory-motivated filterbank, an F0 estimation block, a separation block, and a grouping block, as shown in Fig. [*]. Constraints used in this model are shown in Table 1.
