Figure 9From: Multiple access spatial modulation N t ( u ) =4, N r =1 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. Since the analytical bound is asymptotically tight, at low ABER the dashed and solid lines overlap.Back to article page
