3. Select "Antenna Ports".
The dialog displays the antenna port mapping settings in a table form. The map-
ping table is a matrix with number of rows equal to the number of physical Tx
antennas (Basebands) and number of columns equal of the number of antenna
ports (AP). The available antenna ports depend on the current configuration (see
"TxScheme" > Antenna Ports).
The number of rows depends on the selected "System Configuration".
With the provided settings you can map the antenna ports arbitrarily to the base-
band outputs.
