B.1 Reference point for measurement

38.1083GPPNRRelease 17Satellite Access Node radio transmission and receptionTS

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

The EVM shall be measured at the point after the FFT and a zero-forcing (ZF) equalizer in the receiver, as depicted in figure B.1-1 below.
