{\mathit{N}}_{\mathit{t}}^{\mathbf{\left(}\mathit{u}\mathbf{\right)}}\mathbf{=}\mathbf{4}\mathbf{,}{\mathit{N}}_{\mathit{r}}\mathbf{=}\mathbf{2} and a spectral efficiency of 4 bits/s/Hz. ABER for node 1 using the interference-unaware detector with{\alpha }_{\left(1\right)}^2=1and node 2 with a varying{\alpha }_{\left(2\right)}^2. Dashed lines denote simulation results for node 1 while solid lines denote the analytical upper bound. Since the analytical bound is asymptotically tight, at low ABER the dashed and solid lines overlap.
