Quantifying the Memory Effects of Power Amplifiers: EVM Closed-Form Derivations of Multicarrier Signals

Résumé

This letter deals with the analysis of the memory effects of the Power Amplifier (PA) on multicarrier signals. We analytically derive the expressions of the Error Vector Magnitude (EVM) of amplified signals jointly considering a memory polynomial PA model and clipping effects. We provide analytical EVM expressions that depend on the PA coefficients, PA order, and memory depth as well as the clipping threshold of the input signal. These analytical expressions are new general formulas which allow to predict in-band distortions at the PA output.
