Where:
X and Y are the complex fading variables applied to each path.
E[n] is the expected value of n.
NOTE: Complex Correlation can be used to create correlation values previously
achieved using component or envelope correlation settings.
To create a component correlation of x:
Complex correlation = x + 0i
To create an envelope correlation of x:
Complex correlation = x + 0i
2.13.8. System-Based Correlation
The correlation of Rayleigh fading between units can be set by selecting
Configuration>Correlation Coefficient Between Units or clicking the Correlation
Coefficient between Units icon
in the toolbar.
Figure 2-116: TestKit Configuration Menu
If the Correlation Coefficient type is set to Envelope or Component, the Correlation
Coefficients window displays, as shown in Figure 2-117. In this window, you can set the
Channel to Channel Correlation. The available range for the current coefficient entered
displays at the bottom left of the window.
Figure 2-117: Correlation Coefficient Window
Initially, this window shows all channels as Uncorrelated. You can enter values in any
order. Values entered higher in the matrix affect the range of values lower in the matrix.
Because of range dependencies, we advise you to enter the values from top to bottom by
tabbing through the matrix.
