AbstractThe paper presents the results of a series of computer-simulation tests to determine the effects of non-linear distortion and adjacent channel interference (ACI), on the tolerance to additive white Gaussian noise (AWGN) of a digital satellite modem. The modem transmits a 16-ary differentially encoded quadrature-amplitude-modulated (16-ary DEQAM) signal over a regenerative satellite link, where the high-power amplifier (HPA) at the transmitter may introduce AM-AM and AM-PM conversion effects into the 16-ary DEQAM signal. Three signal constellations are used at the transmitter, namely (1) a conventional 16-ary DEQAM signal constellation, (2) a predistorted 16-ary DEQAM signal constellation and (3) a prerotated 16-ary DEQAM signal constellation. An equivalent baseband model of the transmission system is used to determine the performance of the modem under the various conditions studied, and the results are used to select the preferred modem design.
