# MIMO Performance Evaluation

This application macro is used for calculating mean effective gain (MEG) and envelope correlation coefficient (ECC) for a MIMO antenna configuration. The MEG ratio can also be plotted.

The application macro is used for calculating mean effective gain (MEG), envelope correlation coefficient (ECC)1. Using the Maths option for the 2D graph, the MEG ratio can also be plotted.

Currently, the application macro only supports two channel MIMO: the two channels are simulated as two separate configurations, each with its far field request. You can choose to sweep the cross polarization ratio (XPR), sweep the frequency or both. The propagation environment can also be defined. The default is uniform, with ${P}_{\phi }={P}_{\theta }=\frac{1}{4\pi }$ .

Plots of ECC against XPR or MEG against frequency are plotted depending on the selected options.
