Figure 5From: Single-user MIMO versus multi-user MIMO in distributed antenna systems with limited feedback Comparison of the ASE achieved with SU-MIMO and MU-MIMO employing different CSI feedback algorithms. Area spectral efficiency obtained with SU-MIMO and MU-MIMO transmission utilizing the presented CSI feedback algorithms. The performance of the 2−2/3 DAS configuration is compared to the one achieved in the centralized 8−0/0 system.Back to article page
