Abstract
In this paper, transponder non-idealities are modeled. For this purpose, the Saleh model of phase shift and the parabolic model of group delay are utilized. Simulation results show the phase shift and group delay affect the phase of the DVB-S2 signal and consequently change the signal constellation and cause BER degradation. Simulation results determine the maximum allowable phase shift and group delay of the transponder in order to achieve a predefined BER.
