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.
