Swept Notch NPR for Linearity Assessment of Systems Presenting Long-Term Memory Effects

摘要

Mobile and Satellite applications are progressively moving towards broader bandwidths, so nonlinear long-term memory effects manifested by RF Transmitters must not be neglected. This trend evidences the need for more informative and robust broadband linearity metrics.This work proposes swept notch noise power ratio to capture co-channel long-term memory effects, moving the scientific discussion toward the definition of useful metrics for broadband nonlinear memory assessment.
