The Power Imbalance matrixes provide a means of adjusting the power balance between fading paths in MIMO configurations. There is a separate matrix for each defined fading path. The values in the matrix are linear (not dB) multipliers acting on the output of the system,
The Power Imbalance tab includes two matrixes:
Non-LOS (NLOS) - affects the paths that have fading applied .
Line-of-Sight (LOS) - affects the non-faded paths (e.g., a Ricean direct ray, or a pure Doppler path, or a Rayleigh path with Doppler = 0). If there is no LOS path, this matrix is not used. (Note: The LOS AoA represents the direction of travel and is not used in the LOS Power Imbalance calculation.)

The Power Imbalance matrixes are editable when Correlation Source is set to Custom Correlation Matrix. The matrixes are read-only for all other Correlation Source settings. |
You can view the power imbalance matrices for an individual path or select all of the paths that are enabled in the Fader Path setups. The elements within the power imbalance matrices will either have a real, non-negative value which may be greater or less than one.
The value entered in the matrix field is a representation of the percentage of power applied to the path (or paths, if All Enabled Paths is selected).
A blank cell indicates that the power imbalance values are not identical for all the enabled paths when All Enabled Paths is selected.
