Algorithm 1 Proposed algorithm.

Initialize ${\mathbf{P}}^{(m)}$, ${\mathbf{A}}^{(m)}$, ${\mathbf{Q}}^{(m)}$, and $m=0$ repeat  ${\overline{R}}_k^{\mathrm{old}}={\overline{R}}_k({\mathbf{P}}^{(m)},{\mathbf{A}}^{(m)},{\mathbf{Q}}^{(m)})$, $\forall k$  Find ${\mathbf{P}}^{(m+1)}$ by solving $(\mathbf{P}\mathbf{1})$ for given $\{{\mathbf{P}}^{(m)},{\mathbf{A}}^{(m)},{\mathbf{Q}}^{(m)}\}$  Update $\mathbf{X}$ using (15), and find ${\mathbf{A}}^{(m+1)}$ by solving $(\mathbf{P}\mathbf{2})$ iteratively until convergence for given    $\{{\mathbf{P}}^{(m+1)},{\mathbf{A}}^{(m)},{\mathbf{Q}}^{(m)}\}$  Update $\mathbf{X}$ using (15), and find ${\mathbf{Q}}^{(m+1)}$ by solving $(\mathbf{P}\mathbf{3})$ iteratively until convergence for given    $\{{\mathbf{P}}^{(m+1)},{\mathbf{A}}^{(m+1)},{\mathbf{Q}}^{(m)}\}$  ${\overline{R}}_k^{\mathrm{new}}={\overline{R}}_k({\mathbf{P}}^{(m+1)},{\mathbf{A}}^{(m+1)},{\mathbf{Q}}^{(m+1)})$, $\forall k$  Update $m\leftarrow m+1$ until Convergence, $|{\sum }_{k\in \mathcal{K}}ln({\overline{R}}_k^{\mathrm{new}})-{\sum }_{k\in \mathcal{K}}ln({\overline{R}}_k^{\mathrm{old}})|<ϵ$
