RFMXLTE_ATTR_MODACC_FFT_WINDOW_TYPE

Data Type: int32
Access:read/write
Functions:RFmxLTE_SetAttributeI32
RFmxLTE_GetAttributeI32
Description: Specifies the FFT window type used for the EVM calculation for the ModAcc measurement.

Refer to the LTE Modulation Accuracy (ModAcc) topic for more information about FFT window type.

The default value is RFMXLTE_VAL_MODACC_FFT_WINDOW_TYPE_CUSTOM.

Get Function: RFmxLTE_ModAccGetFFTWindowType
Set Function: RFmxLTE_ModAccSetFFTWindowType
Values:
RFMXLTE_VAL_MODACC_FFT_WINDOW_TYPE_3GPP (0)The maximum EVM between the start window position and the end window position is returned according to the 3GPP specification. The FFT window positions are specified by the attribute. Refer to the Annexe E.3.2 of 3GPP TS 36.521 specification for more information on the FFT window.
RFMXLTE_VAL_MODACC_FFT_WINDOW_TYPE_CUSTOM (1)Only one FFT window position is used for the EVM calculation. FFT window position is specified by RFMXLTE_ATTR_MODACC_FFT_WINDOW_OFFSET attribute.
