Consider a training-based communication system with data power ratio $\alpha$ and effective signal-to-noise ratio $\rho_{\rm eff}$. Let $\alpha_\star$ be the power allocation that…

Let $\rho_{\text{eff}}$ denote the effective signal-to-noise ratio, and let $\widetilde{\rm{MSE}}_{\text{\tiny{Box-RLS}}}$ and $\widetilde{\rm{SEP}}_{\text{\tiny{Box-RLS}}}$ denote…
