Algorithm 1 LPI-Based Optimal Power Allocation Strategy

1:Initialization: ${\delta }_{\mathrm{FA}}$, ${\delta }_{\mathrm{D}}$, $P_{\mathrm{Total}}$, $r_{\mathrm{th}}$, iterative index $n=1$;   2:Loop until ${\mathit{P}}_{\mathbf{rad}}$ converges:    Calculate $P_{\mathrm{com}}$ by solving (16);    Calculate $P_{\mathrm{rad}}^{\left(n\right)}$ via bisection search in Algorithm 2;    Calculate $p_{\mathrm{D}}^{\left(n\right)}\leftarrow \left(\sqrt{2P_{\mathrm{rad}}^{\left(n\right)}{\gamma }_{\mathrm{rad}}},\sqrt{2\lambda }\right)$; 3:End loop   4:Update: Update $P_{\mathrm{com}}^{*}\leftarrow P_{\mathrm{com}}$, $P_{\mathrm{rad}}^{*}\leftarrow P_{\mathrm{rad}}^{\left(n\right)}$.
