Frame Part Parameters (Custom OFDM)

Name sets name of the selected frame part (limited to 30 characters).

MIMO Configuration

MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. Configuration contains parameters that specify the frame part's active port count and channel estimation settings.

Active Port Count indicates the active pilot (or preamble) port count used for SISO/MIMO demodulation of this Frame Part's data allocation content. A value of 0 indicates this Frame Part's data allocations are not configured with any active pilot (or preamble) ports. A value of 1 indicates this Frame Part's data allocations are configured with a single active pilot (or preamble) port supporting demodulation of single stream (SISO) data transmissions. A value of N > 1 indicates this Frame Part's data allocations are configured with N active pilot (or preamble) ports potentially supporting demodulation of up to N multiple stream (MIMO) data transmissions.

Default: 0

Range: 0 to (total Transmitter Antennas)

Channel Estimation CDM Group

Subcarrier Count sets the subcarrier count per channel estimation CDM (Code Domain Multiplex) grouping unit used to despread this Frame Part's MIMO pilot (or preamble) allocations in the code domain if they share an overlapped symbol/subcarrier allocation pattern.

This property is required for CDM overlapped MIMO pilot (or preamble) configurations. A value of N means that for each pilot (or preamble) symbol, the pilot (or preamble) values on N adjacent pilot (or preamble) subcarriers are used together to estimate the channel response, and this estimation result is applied to all the N adjacent pilot (or preamble) subcarriers.

This property along with Symbol Count decide the size of channel estimation CDM grouping unit in time domain and frequency domain.

Default: 1

Symbol Count sets the symbol count per channel estimation CDM (Code Domain Multiplex) grouping unit used to despread this Frame Part's MIMO pilot (or preamble) allocations in the code domain if they share an overlapped symbol/subcarrier allocation pattern.

This property is required for CDM overlapped MIMO pilot (or preamble) configurations. A value of N means that for each pilot (or preamble) subcarrier, the pilot (or preamble) values on N adjacent pilot (or preamble) symbols are used together to estimate the channel response, and this estimation result is applied to all the N adjacent pilot (or preamble) symbols.

This property along with Subcarrier Count decide the size of channel estimation CDM grouping unit in time domain and frequency domain.
