Figure 5From: Multiple access spatial modulation N t ( u ) =4, a varying N r and a spectral efficiency of 4 bits/s/Hz. ABER for node 1 using the interference-unaware detector with α ( 1 ) 2 =1, node 2 with α ( 2 ) 2 =0.1and node 3 with α ( 3 ) 2 =0.01. All presented curves are for node 1 unless otherwise stated in the legend. Dashed lines denote simulation results for node 1 while solid lines denote the analytical upper bound. We note that the addition of more receive antennas reduces the ABER and hence closes the gap between the analytical and simulation results.Back to article page
