AbstractThe paper studies a digital modem that transmits a rate-3/4 convolutionally encoded 16-ary amplitude and phase modulated (CE16APM) signal, over a regenerative satellite link. The signal uses a (4, 12) circular signal constellation set and has a coding gain of about 4 dB at a bit error rate of 10-4, over an uncoded eight-phase-shift keyed (8PSK) signal. Several different earth stations are assumed to have simultaneous access to a given regenerative satellite using frequency division multiple access. Thus, the CE16APM signals that occupy the immediately adjacent frequency bands can introduce adjacent-channel interference (ACI) into the transmitted CE16APM signal. The high-power amplifier (HPA) at each of the earth-station transmitters or on board the satellite transmitter may introduce nonlinear AM-AM and AM-PM conversion effects into the CE16APM signal. Results of a series of computer-simulation tests are presented.
