STC/MIMO Tab (IEEE 802.16 OFDMA)

Menu Path: MeasSetup > IEEE 802.16 OFDMA Demod Properties > STC/MIMOtab

The STC/MIMO tab contains parameters that specify the Space Time Coding (STC Space Time Coding (STC) allows the transmitter to transmit signals (information) both in time and space, meaning the information is transmitted by two antennas at two different times consecutively.) and Multiple In Multiple Out (MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas.) signal type configuration parameters.

The STC/MIMO parameters are only available when a mutiple antenna STC zone type is specified. The STC type is specified on the Downlink Zone Definition panel.

STC/MIMO tab parameters are:

• Measure Input Channel 
• Enable Matrix Decoder
  • Measure Matrix Stream 
• Override Transmit Antenna Pilot Pattern
• Enable Cyclic-Delay Diversity (CDD) Measurement 
• Include inactive Antenna Paths on MIMO Traces 
• Normalize each MIMO Path in Frequency Response

STC\MIMO Trace Data

The following STC/MIMO related trace data results are available when multiple antenna STC zone type measurements are selected:

• MIMO Info Trace Data
• MIMO Ch Freq Resp Adj Diff Trace Data
• MIMO Ch Frequency Response Trace Data
• MIMO Common Pilot Error Trace Data
• MIMO Eq Cond Number Trace Data
