Description
How does oscillator phase noise degrade Error Vector Magnitude (EVM) in 5G NR waveforms? This talk presents a step-by-step methodology to predict that impact—starting from a modeled phase noise spectrum and ending with EVM performance metrics for a 5G NR OFDM signal.
We show how to calculate the expected EVM from vibration-induced phase noise using known system parameters, and validate these predictions through full waveform simulations at 6.05 GHz. The approach links oscillator g-sensitivity, vibration profiles, and spectral characteristics to real impairments in constellation quality.
Attendees will gain a practical framework for anticipating and evaluating phase noise effects in 5G systems and SDR-based test environments.
