MIMO Channel Capacity in 2D and 3D Isotropic Environments

Figure 3

Comparison of the capacity CDFs for multiple orientations of the two-element antennas in statistically isotropic environments. Each plot compares the 2D environment’s orientation-dependent capacity CDFs, the 2D environment’s orientation-combined capacity CDFs, and the 3D environment’s orientation-independent capacity CDFs.
