Figure 10From: Multiple access spatial modulation N t ( u ) =4, N r =3 and a spectral efficiency of 4 bits/s/Hz. ABER for node 1 with α ( 1 ) 2 =1, node 2 with α ( 2 ) 2 =0.1and node 3 with α ( 3 ) 2 =0.01.Ana (N(u)) denotes the analytical upper bound for node u. The analytical bound is again shown to be asymptotically tight at low ABER.Back to article page
