Configures the equalizer.
Syntax
Namespace: NationalInstruments.RFmx.DemodMX
public int ConfigureEqualizer(string selectorString, RFmxDemodMXDDemodEqualizerMode equalizerMode, int equalizerFilterLength, double x0, double dx, ComplexSingle[] y, int equalizerTrainingCount, double equalizerConvergenceFactor)
Remarks
This method maps to the RFmxDemod_DDemodCfgEqualizer() function in C.
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Pass an empty string. The signal name that is passed when creating the signal configuration is used. |
| equalizerMode | RFmxDemodMXDDemodEqualizerMode | Specifies whether the measurement needs to perform equalization. |
| equalizerFilterLength | int | Specifies the length of the equalization filter to be computed. The length is specified in terms of symbols. This parameter is ignored when the equalizer initial coefficients are specified. |
| x0 | double | Always pass 0 to this parameter. Any other values will be ignored. |
| dx | double | Specifies the spacing between the coefficients as a fraction of the symbol spacing. For example, if four coefficients correspond to one symbol, the spacing is 1/4. |
| y | ComplexSingle[] | Specifies the initial coefficients to be used by the equalizer. |
| equalizerTrainingCount | int | Specifies the number of iterations during which the equalizer adapts its coefficients in the training stage. |
| equalizerConvergenceFactor | double | Specifies the incremental step used by the equalizer to adapt to the channel, during the training stage. |
Returns
Returns the status code of this method. The status code either indicates success or describes a warning condition.
