Efficient Simulation of Nonlinear Effects on Multicarrier Signals

Multicarrier signals are know to be very prone to nonlinear effects due to their high envelope fluctuations. This makes the simulation of multicarrier systems, required for its per- formance evaluation and/or its optimization, very complex due to the high oversampling requirements inherent to the significant spectral widening associated to commonly used nonlinear characteristics. In this paper we present an effi- cient approach for the performance evaluation of multicar- rier systems with nonlinear transmitters. It is shown that we can accurately simulate nonlinear effects in multicarrier signals without the need for high oversampling.
