Equalizer Settings (6GR)
The section of the Advanced tab controls equalizer training. All parameters are auto-coupled — see Auto and Manual Parameter Coupling.
EQ Signal Basis - Selects which signal content the equalizer trains on.
- None - Equalizer training is off.
- RS - Equalizer training is based on the reference signal.
- RS+Data - Equalizer training is based on the reference signal and data.
Default: RS
Choices: None, RS, RS+Data
EQ Time Basis - Selects the time span the equalizer trains over.
Default: Per Frame
Choices: Per Subframe, Result Length, Per Slot, Per Frame, Contiguous Slots
MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. EQ Signal Basis - The equalizer training signal basis for MIMO analysis.
Default: RS
Choices: None, RS, RS+Data
Layer EQ Moving Average / Layer EQ Moving Avg Length - Enable moving-average smoothing of the per-layer equalizer estimate, and set its length in subcarriers. The length is constrained to an odd number, and applies only when 3GPP EVM (Conformance) is off and the moving average is on.
Default: Enabled, length 19 subcarriers
Range: 1 to 4095 subcarriers (odd values)
MIMO EQ Time Basis - The equalizer training time span for MIMO analysis.
Default: Per Frame
Choices: Per Subframe, Result Length, Per Slot, Per Frame, Contiguous Slots
MIMO EQ Moving Average / MIMO EQ Moving Avg Length - Enable moving-average smoothing of the MIMO equalizer estimate, and set its length in subcarriers (odd values). The length applies only to a MIMO carrier with the moving average on.
Default: Cleared, length 7 subcarriers
Range: 1 to 4095 subcarriers (odd values)
While 3GPP EVM (Conformance) is on, this section is collapsed and every parameter in it is unavailable, because conformance EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format. fixes the equalizer settings. The section header says so. Clear 3GPP EVM (Conformance) to set them yourself.
