Use of equivalent nonlinearities for studying quantisation effects on sampled multicarrier signals

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