Figure 3From: Multiple access spatial modulation N t ( u ) =4, N r =2 and a spectral efficiency of 4 bits/s/Hz. ABER for node 1 using the interference-unaware detector with α ( 1 ) 2 =1and node 2 with a varying α ( 2 ) 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.Back to article page
