AbstractThe paper studies a digital modem that transmits a convolutionally encoded eight-phase-shift-keyed (CE8PSK) signal over a satellite link. Several different earth stations are assumed to have simultaneous access to a given transponder in the satellite, in an arrangement of frequency division multiple access. Thus, adjacent channel interference (ACI) can be introduced into the CE8PSK signal by the corresponding CE8PSK signals that occupy the immediately adjacent frequency bands. The high power amplifier (HPA) at the earth station transmitter, within the satellite link, may introduce nonlinear distortion into the CE8PSK signal, but the satellite transponder is assummed to be linear. Predistortion may or may not be used. Results are presented of an extensive series of computer-simulation tests. These measure the effects of bandlimiting, nonlinear distortion with and without predistortion, ACI and the demodulation process at the receiver, on the tolerance of the modem to additive white Gaussian noise.
