Design Notes

5G EVM and ACPR Analysis

This example demonstrates EVM and ACPR measurements for a 5G link similar to Verizon's prelimnary 5G specifications for 28GHz operation ( The link includes FBMC modulator and demodulator, linear preamplifier, phase noise model, and a nonlinear power amplifier.

This example shows:

FBMC modulator/demodulator configured to occupy 100MHz with 75kHz subcarrier spacingPhase noise model specified as data fileBehavioral nonlinear amplifier modelACPR vs PA input power measurementEVM vs PA output power measurementAM to AM, instantaneous power and operating point measurements

VSA named "EVM_FBMC" controls the power sweep. In this case, the FBMC modulator output power is swept from -12 to 12 dBm at 2dBm steps. The progression of transmit spectrum, PA output spectrum, and received IQ constellation can be observed while the simulation is running.
