${\mathit{N}}_{\mathit{t}}^{\mathbf{\left(}\mathit{u}\mathbf{\right)}}\mathbf{=}\mathbf{2}\mathbf{,}{\mathit{N}}_{\mathit{r}}\mathbf{=}\mathbf{3}$ and a spectral efficiency of 4 bits/s/Hz. ABER using the interference-aware detector for node 1 with${\alpha }_{\left(1\right)}^2=1$and node 2 with${\alpha }_{\left(2\right)}^2=0.1$.Ana (N_(u)) denotes the analytical upper bound for node u. Since the analytical bound is asymptotically tight, at low ABER the dashed and solid lines overlap.
