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

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 a 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.
