Analytical Simulation of Nonlinear Satellite Links

Abstract

Performance predictions for nonlinear digital satellite channels are usually obtained by either purely analytical methods or Monte Carlo simulations. These approaches must work with very simple channel models or they become extremely costly to use. In this paper it is shown that through analytical modeling of the effect of the nonlinearity on the uplink waveform it is possible to obtain approximate performance predictions with a minimum of computer time. It is demonstrated that the results agree quite well with Monte Carlo simulations and that meaningful tradeoffs can be, performed with this tool.
