Abstract

A model for the semi-analytic performance evaluation of digital satellite radio links in the presence of interference on both the uplink and the downlink is presented. Error probability on the linear portion of the link is estimated using simulation to determine the moments of the interfering signal samples and analyzing the effect of an undetermined phase difference among carriers. The nonlinear portion of the link is modeled using a series expansion of the nonlinearity; the output terms are then separated, allowing construction of the conditional probability densities required in the error probability computation. Results are carried out for M-QAM (M-ary quadrature amplitude modulation) and M-PSK (M-ary phase-shift keying) modulation systems
