3 VMA Mode
3.2 Custom OFDM Measurement
MIMO Scheme
Enables you to specify and configure MIMO scheme.
MIMO Type
Specify MIMO type according to how reference signal (preamble/pilot) generated. it
is assumed that data subcarriers are transmitted simultaneously on all antennas,
and have the same modulation format on all antennas.
–
Non-overlapping: Any given pilot or preamble subcarrier is transmitted on only
one antenna at a time, and is null on all other antennas. (Examples: WiMAX, LTE)
–
Overlapping All: All preamble and pilot subcarriers are transmitted on all
antennas at all times. (Example: 802.11n)
