Use of Equivalent Nonlinearities for Studying Quantization Effects on Sampled Multicarrier Signals

Abstract

The large dynamic range of multicarrier signals make them very sensitive to quantization effects. Due to the non-continuous nature of quantization curves, conventional analytical methods used to characterize the distortion effects of quantization signals are very complex, and can and even have convergence and/or accuracy problems. A simple and accurate analytical method for the performance evaluation of quantization effects on sampled multicarrier signals is presented in this paper.
